896HD only successfully connects in jackd at 192000

This is using 2.0~rc2+svn1569-2ubuntu1 and jackd 0.116.1-4ubuntu2 in Ubuntu Karmic

I think there are two separate problems being reported here.

The first is the error when starting ffado-mixer with the 896HD set to 4x mode. Svn r1767 contains a fix which should address this.

The issue of jackd "failing" with your 896HD when not set to a 4x rate requires more investigation. Certainly the 896HD has worked at 1x and 2x rates in the past so I doubt there's a huge problem involved. To start with, could you please describe in more detail what happens when you try to start jackd at a 1x or 2x rate, along with the jackd command line you used to start jackd? If any error messages are reported by jackd could you please provide them. Finally, could you please run jackd including "-v 5" somewhere after the "-d firewire" option; this will provide additional debugging output and perhaps give a better idea of what exactly is going wrong.

Could you also please provide the output of the "uname -a" command when run in a terminal?

Note: r1768 addresses the 4x rate mixer bug in the 2.0 branch.

both r1768 and r1767 resolve the ffado-mixer issue (same fix actually.)

below are jackd at 44100, 96000 and 192000. Notice that for some reason 192000 does not work now either. It is the only setting that worked in the past, but even then it was finicky and I don't know why it did. Previously, I used the gui program Jack Control and I pulled the jackd line from the .jackdrc file.

If I turned my unit off and back on then I can get the following to work: # /usr/bin/jackd -R -dfirewire -r192000 -p512 -n3 -v5

No such luck so far on 44100 and 96000

Thanks for the update and confirmation that the ffado-mixer issue is resolved.

There's nothing obvious in the "-v 5" output that points to a specific issue. Could you repeat using "-v 6" and give me the output. Note that this could produce a lot of output, so it might be more convenient to attach the logfile rather than putting it inline as you have done up to now. You'll find the "attach file" button right under the end of the initial bug report.

Oh, the reason your 192k attempt failed was a side-effect of the previous crashes. Those sessions had reserved bandwidth on the bus but, due to the crash, not released it. By the time the 192k test rolled around most of the bus's bandwidth was already reserved; when it then tried to reserve some more the request was rejected and jackd exitted. By turning the unit off and then back on again the bus was reset, all previous allocations were forgotten and therefore things could proceed normally.

If you do put it inline, could you put it inside a "code" block. You can start a code block using the "code block" button on top of the edit box you use to compose your comment. Doing this means that line breaks will be preserved in the log output which will make it much easier to decipher.

In addition to the above test, could you tell me more about your firewire card that you're using. In the first instance the section about the firewire card reported in the output of the "lspci -v" (or "/sbin/lspci -v" command is probably adequate.

One more thing: could you perhaps re-test after adding "-P70" to the first part of your jackd command. We'll also increase the size and number of the buffers too, just for testing. So with this in mind your jackd command should be something like this:

/usr/bin/jackd -R -P70 -dfirewire -r44100 -p1024 -n4 -v6

In terms of the jackd/ffado that you're running, I assume you're using versions supplied by Ubuntu (as opposed to versions you've compiled yourself).

08:01.0 FireWire? (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev 05) (prog-if 10)

Subsystem: ASUSTeK Computer Inc. Device 8264 Flags: bus master, medium devsel, latency 64, IRQ 16 Memory at fbffe800 (32-bit, non-prefetchable) [size=2K] Capabilities: <access denied> Kernel driver in use: ohci1394 Kernel modules: firewire-ohci, ohci1394

I am using the jackd/ffado supplied in the latest Ubuntu Studio 9.10 (Karmic) 64 bit (with upgrades)

I will upload the dumps using the command you created for 44100, 96000 (both fail) and 192000 (succeeds and then is manually killed)

Thanks for the logging dumps for the three sample rates. There does appear to be something strange happening; not only does 192k appear to work, but the failure mode for 1x and 2x rates are different (one segfaults, the other triggers a glibc double-free check). I will give all this some thought - nothing immediately springs to mind. Given that you're using the Ubuntu packages I assume that there's no chance of old jack/ffado libraries lying around on the system which might be confusing things. It's probably worth checking though; do an "ls -l" of /usr/lib/ and look for libffado* and libjack*. For each library there should be only one library and 2 or so symbolic links to that library. For example, on my system I have

  libffado.so -> libffado.so.2
  libffado.so.2 -> libffado.so.2.999.0
  libffado.so.2.999.0
  libjack.so -> libjack.so.0.0.28
  libjack.so.0 -> libjack.so.0.0.28
  libjack.so.0.0.28

The firewire controller you are using has proven to be a bit of a mixed bag - for most people it doesn't seem to work at all while for a handful it appears 100% reliable. For the moment I will put this to one side though - since 192k works for you the firewire controller must be doing something right.

On a related note, your ticket #246 talks about the channels available being limited to the 8 analog ins/outs. Given the nature of this ticket I suspect this was at 192k, in which case it is not an error that only these channels are available according to my information about the device. As far as I know the 896HD does not provide a separate headphones channel at 4x rates, so there will not be a jack port created for the headphone mix. If you have information to the contrary please let me know - otherwise I will close #246 as not-a-bug since the behaviour is what is expected at 4x rates.

The firewire controller works fine in windows as far as I can tell.

Since I have only gotten 4x rate to work, #246 does not appear to be a bug. I confirmed it in Windows where I would record it in 192000 and then when I would route playback to the headphones, it would automatically switch the unit back to 44100.

As I mentioned, the fact that you can get a 4x rate to work tends to rule out the firewire card. It should however be noted that there are cards which work fine under other operating systems but not under Linux because the drivers in those other OSes have the advantage that chipset makers tell them workarounds for silicon problems. In any case, I don't at this stage believe your problems are due to your firewire chipset.

Thanks for confirming your libraries. I will look into this in more detail and get back to you. Stay tuned.

Finally, for completeness, I take it from an earlier comment of yours that you have tried the current svn revision or the 2.0.0 release (as opposed to 2.0rc2) and that the problem still exists in that. Can you confirm this for me at your convenience?

No, I have only tried the stock drivers that came with the distro. I am willing to do it though. Are there any issues that I should be concerned with? Will I need to recompile jackd or any other programs also?

Ah right. Well, I guess we probably ought to try at least the 2.0.0 release so I know precisely which code is giving trouble. However, since 2.0.0 isn't packaged by the distributions yet we might as well go with the latest svn trunk snapshot (which is r1768 at present). That's also the version on my development machine at present, so it will make further investigations easier from my point of view.

You shouldn't need to recompile jackd or anything else at this stage - only ffado itself. To be consistent with the rest of your system you probably want to install the new ffado in the same general places as the existing one is in. So do

  scons PREFIX=/usr

when configuring/compiling. When you do "scons install" this should overwrite the existing ffado things with the new version. However, to make sure the libffado libraries have done the right thing you might want to look in /usr/lib/ (as you did before), remove any of the old libffado files and make sure the symlinks are pointing to sensible targets.

Ideally you'd use the package manager to remove ffado from your system before installing the new one. However, my understanding is that on distributions such as Ubuntu the removal of ffado will also cause everything that depends on ffado to also be removed - which you definitely don't want. Perhaps there's an option that causes this not to happen but I don't know what it is off-hand (I don't use Ubuntu myself).

Oops, that was with a straight trunk, I move to the stable branch and it compiled..... now to test

No difference. It failed in the same way.

Also, is there a way I could get Beta 7? There was a message on the download page that RC1 broke MOTU.

Hi

There are a few interesting points coming out of your last post. Firstly, straight trunk really should compile without errors. I've just checked the most recent revision out (r1775) and it compiled for me with no issues. Ah, it looks like you might have been unlucky enough to check out in the middle of some changes by Arnold which have since been completed. You could always add "ENABLE_DICE=no" to skip compilation of the DICE driver (which isn't relevant for MOTU interfaces).

Anyway, you then got 2.0.0 which, for the purposes of this exercise, should be identical to trunk. Your tests show that the same problem is present for you with this version, so that gives me something concrete to go on now. Thanks.

In connection with the "MOTU cuemix value parser error", you can safely ignore this for the moment (although this report does remind me to add in a rate limiter for those messages). The MOTU sends details about the front panel controlled settings in a substream of the audio data using a simple key-value arrangement. The message you report is essentially saying that there are some keys sent by the 896HD which we don't currently know about. While I would be interested in working with you to work out what these mean, they are not critical for the device's usability under Linux at this point. Although we decode this substream, the resulting information isn't used by FFADO at the moment.

Your messages output is more or less confirming that jackd is segfaulting for the slower sample rates. It appears that this occurs at the time real data starts to flow which is suggestive of a buffer overflow issue, uninitialised pointer or something. It's curious that it doesn't show for other devices though (at least, not that's been reported anyway). Currently I'm concentrating on the this line of enquiry.

Finally, there's no point in getting beta7 or any of the betas now that 2.0.0 is out. In any case, while 2.0-rc1 did indeed break MOTU, this was well and truly fixed by 2.0-rc2 (which is what you started with) and obviously doesn't affect 2.0.0 release either. At this stage it appears that there is a real issue at work here and we'll try to work out what it is.

Further information: I have now tested r1775 with my device (Traveler) at 44.1 kHz and it appears to be perfectly happy. This is with a jack which reports itself to be 0.116.2 - the same version that you're using. So that more or less leaves two options: the driver for the 896HD has broken sometime since January 2009 (the last time I had someone explicitly confirm to me that the 896HD was working) or that there's been some internal change to ffado which is upsetting the jack binary that is installed on your system.

Your initial report was for jack 0.116.2 with ffado 2.0-rc2. Were these the versions which were originally installed on your system, or had you upgraded ffado to 2.0-rc2 from an earlier version using the Ubuntu package when it became available?

I'm wondering whether it might be worthwhile recompiling jackd against either ffado 2.0.0 or trunk (whichever you have installed at present) and see if that makes any difference. The process here is similar to ffado - specify "./configure --prefix=/usr" to make the newly compiled jackd install over the top of the previous one. After the final "make install" step, confirm that libjack* is as it should be in /usr/lib/.

I've had a look at the 896HD-specific parts of ffado and so far nothing strikes me as being out of place. I shall keep looking though, since it's entirely possible that a gremlin has crept in when we weren't looking. :-)

Some more ideas. Assuming that the recompilation of jackd does not change the symptoms, the next thing to try is to get a core dump from jackd and try to work out the general area of the problem. You can skip the next paragraph if you're familiar with obtaining core dumps and using them in gdb.

To enable core dumps use "ulimit -c 204800" under bash or "limit coredumpsize 204800" under tcsh. Then run jackd in the usual way, requesting the sample rate which gives rise to the segmentation fault (as opposed to the double-free trap). When jackd crashes now it should create a core file (named core*, the "*" portion depending on your configuration - I'll assume it's empty for the rest of this description). We can then use that core file with gdb to at least find out the function that caused the crash. Start gdb with "gdb /usr/bin/jackd core". Typing the "where" command at the gdb prompt should give a listing of the call stack leading to the crash. One can then use "print" to display variable values in the faulting function, and so forth. Unless memory has been badly corrupted this might give a clue as to what went wrong.

I realise the above is rather brief - if you need further information about any of this please let me know and I'll expand as needed.

This is strange.

I compiled and installed jack 0.118.0. I actually got 44100 to work for a while when I manually started it (curiously 96000 still failed). Then I went to qjackctl to try it and actually got it to work once. Then after trying it again at 96000 and having it fail, from then on 44100 would segfault. No amount of rebooting the computer or the 896hd would get it to work again. I actually thought I had it working after the initial compile of ffado and then when I went to test for 96000 (failed) and went back to 44100 it then failed also in the same way.

Capture 1-14 and playback 1-14 are not very helpful when using the mappings. It would be much more useful if you used the default firewire capture and playback names such as: pbk_Phones-L pbk_Phones-R pbk_Analog1 pbk_Analog2

cap_Analog1 cap_Analog2 etc

Thanks for the extensive report.

I compiled and installed jack 0.118.0. I actually got 44100 to work for a while when I manually started it (curiously 96000 still failed). Then I went to qjackctl to try it and actually got it to work once. Then after trying it again at 96000 and having it fail, from then on 44100 would segfault. No amount of rebooting the computer or the 896hd would get it to work again.

It is the intermittant nature of the behaviour which has me thinking that there's a memory corruption occuring with the 896HD for some reason.

Note that when debugging ffado it's most useful to add the "-v 5" to the command line sometime after the "-dfirewire" option. This tells libffado to output extensive debugging messages. The "-v" before "-dfirewire" just tells jackd itself to be verbose which, for tracking down this particular problem, might not be all we need.

This is interesting - the double-free is being detected in the transferSilence() method but that function doesn't call free() AFAIK. It adds weight to my hypothesis that there's some memory corruption going on which is in some way triggered only when the 896HD is in use.

896hd has all 8 programmable meters and the 2 main outs lit up half way (from 42 to 18) after the fail and needs to be rebooted.

Yes, this will happen with the MOTUs without too much effort at all. If an audio packet is missed or arrives too late (ie: there's a loss of sync between the PC and the device) the interfaces get into this strange state. If you were to listen to the outputs you'll probably hear a high-pitched tone from some of them. With a working ffado, a restart of jackd will clear the condition.

One other thing. When it does work, then it will show:

Capture 1-14 and playback 1-14 are not very helpful when using the mappings. It would be much more useful if you used the default firewire capture and playback names such as:

> pbk_Phones-L
> pbk_Phones-R
> pbk_Analog1
> pbk_Analog2
> 
> cap_Analog1
> cap_Analog2
> etc

The default names of the ports are mandated by JACK - we can't do anything about the fact that the ports are called capture_1 and so forth. It doesn't affect just FFADO though - all sound interfaces have the same issue. It is a topic which has come up multiple times on the jackd lists. The JACK developers have their reasons for this (mostly related to portability of software sessions across PCs with different interfaces).

What we can control are the port aliases though - these are set to more useful names ("Phones-L" and so forth). You can view these using "jack_lsp -A" when jackd is running; it gives the port name (eg: "system:capture_3") and lists the aliases for that port ("Analog-1"). This way you can at least cross-reference the port names.

So in summary, the names of the jack ports are controlled by JACK, not the backend (of which FFADO is one).

I'll continue my musings following your gdb post.

Replying to sireasoning:

I am unfamiliar with gdb but here is some of what you asked for. I could not figure out what to do with the print command though

That's fine - it's a good start and we can build on that.

Ok, it seems that the segfault occurs when something goes very wrong with the receive side of things. Conversely we've seen the double-free/corruption trigger only on the transmit side.

To use the print command, one simply requests the variable name to print. The variables available are those visible to the function where gdb is currently focused. By default it will be focused on the top-most function listed in the call trace (# 0, memcpy in this case). What we need to do is move the focus to a more useful function and investigate the arguments passed to memcpy() from there.

Working from the above example, use the "down" command 3 times (or is it "up" - I can never remember) to move to the processPacketData() method. We can now view the values of variables visible to that function (looking at the source code is useful at this point). In the first instance I am interested to know the values of length, data and m_last_timestamp, so we use the commands "print length", "print data" and "print m_last_timestamp".

What I am suspecting is that the packets being sent to/from the 896HD are not quite the size that we are expecting. Knowing the value of the "length" variable in particular will go some way towards proving (or disproving) this theory.

Replying to jwoithe:

You shouldn't need to recompile jackd or anything else at this stage - only ffado itself. To be consistent with the rest of your system you probably want to install the new ffado in the same general places as the existing one is in. So do

   scons PREFIX=/usr

when configuring/compiling. When you do "scons install" this should overwrite the existing ffado things with the new version. However, to make sure the libffado libraries have done the right thing you might want to look in /usr/lib/ (as you did before), remove any of the old libffado files and make sure the symlinks are pointing to sensible targets.

As pointed out by Arnold in an email to the user/devel lists on 31 Dec 2009, the above is not quite right when upgrading a system from a 2.0-rc release to the 2.0.0 release (or trunk). The problem is that on systems which ship a pre-2.0 FFADO release candidate, jackd links to libffado.so.1. FFADO 2.0.0 (and trunk) instead create libffado.so.2, so installing these won't install anything that will be used by jackd and jackd will continue to use the old libffado.

A short-term solution, as suggested by Arnold, is remove libffado.so.1 and create a symlink of this name to libffado.so.2 ("rm libffado.so.1 ; ln -s libffado.so.2 libffado.so.1"). A more permanent solution on these systems might be to recompile jackd against the new libffado.

Of course once distributions pick up the new FFADO release none of this trickery will be required.

In relation to the system presently being discussed, this library version issue is probably going to be an issue. Double check /usr/lib/, and if libffado.so.1 does not eventually refer to the new libffado provided by the 2.0.0 compilation the symlink trick noted above would be the way to go.

I had actually caught the libffado.so.1 issue early as I noticed that the jackd did not show "libffado 2.0.0-1768". I changed the link from libffado.so to link with libffado.so.2. However I did not change the libffado.so.1 link. I have now done that and will recompile jack.

after recompilation of jack I get the following:

FWIW, I changed directories (as I was starting jackd in the same directory I built it in) and temporarily got it looking like it would work. I then opened qjackctl and connected the capture and playback (system to system). So far so good, but when I tried to create a new session in Ardour ffado segfaulted immediately. Below is the gdb on that, but to my eyes it looks the same as the last one I sent:

Firstly, good catch on the library version thing.

Secondly, the reason why the print commands are reporting "no symbol" is possibly because your FFADO doesn't include debug symbols. To address this, recompile ffado and include "DEBUG=yes" on your scons command line (you don't need to repeat any previously specified options since scons will remember those). Sorry about forgetting about this - the default is to have debug turned off but due to scon's aforementioned memory of command line options I tend to overlook that. Install this new version and then repeat the gdb stuff. Note that you'll more than likely have to rerun jackd/ffado to regenerate a core dump which is applicable to the new binary (which will now include debug symbols).

I upgraded svn to the latest ffado, I then rebuilt it with debug but still did not get debuggin info, so I tried to rebuild jack with the latest ffado, but it fails to build. Below is the jack configure and make:

Replying to sireasoning:

I upgraded svn to the latest ffado, I then rebuilt it with debug but still did not get debuggin info

That is extremely odd. Did you check that the newly build libffado was installed correctly into /usr/lib/? Specifying "DEBUG=yes" should cause the compilation commands to include "-g" and "-Wall" and therefore libffado at least should include debugging symbols. A bunch of other libraries still won't (and will continue to be reported as such when you start gdb) but that shouldn't matter - since we are interested in symbols from libffado, symbols in libffado is all we need. I assume you retried the down/print command sequence in gdb and observed it failing. If not it would be worth doing since the symbols we want might well be present now.

Perhaps the fact that jackd isn't built with debug symbols is in some way affecting the overall core dump though, so your idea to try to compile a debug version of jackd makes sense. Now I come to think about this I have a vague recollection of having encountered something like this myself some time ago.

so I tried to rebuild jack with the latest ffado, but it fails to build. Below is the jack configure and make:

The configure output looks fine at first glance. There are a few optional libraries not found (or probably more accurately, the -devel package of the libraries aren't found) but that shouldn't stop jackd building.

> $ sudo make --debug
> :

Note that unless you extracted the source code with "sudo" you shouldn't need to use sudo to do the main "make" step. The "sudo" bit should only be needed when you do "make install".

It's been a while since I've compiled jackd, but I think you need to do include "--enable-debug" in your argument list to "./configure" to enable debug messages. Then do "make" to build it and finally "sudo make install" to install it. Specifying "--debug" on the end of "make" will cause make itself to output debugging information about the build process, which isn't necessarily what we want or need.

I've just tried this on my machine at work and I didn't encounter this error. Looking at the location of the error in the jackd source (libjack/client.c, line 1472) I notice this:

  DEBUG ("client polling on %s", client->pollmax == 2 ? x
         "event_fd and graph_wait_fd..." :
         "event_fd only");

So firstly it seems you did include "--enable-debug" when configuring jackd - otherwise the DEBUG() macro expands to an empty string. The cause of the error would be that "x" at the end of the line. It shouldn't be there as far as I can tell. Get rid of it and then compilation should proceed.

Here we go:

Good job. So, the length of the packet delivered by the 896HD in this situation is 424 bytes.

Now, based on its understanding of the device FFADO is expecting 14 audio channels (I'm assuming the basic device setup hasn't changed from an earlier verbose run). Each of these is 3 bytes, so there's 42 bytes of audio data. Each frame also has a futher 10 bytes of auxilary data, bringing the expected frame size to 52 bytes. Each packet at 1x rates includes 8 frames and there's an additional 8 bytes of header info, so that means FFADO expects a frame size of 8*52+8 = 424. So there's agreement there.

Looking further up the call chain I note that the number of bytes to write into the ringbuffer is 416 (the cnt argument to ffado_ringbuffer_write()). This is also correct: 424-8. When writeFrames() is called it is told there are 8 frames which is also right. So certainly the size accounting is working correctly.

The line triggering the segfault is the memcpy() on line 273 of ringbuffer.c, in the function ffado_ringbuffer_write(). So we need to find out the value of some variables in this function now. After starting gdb, one "up" command should place you in ffado_ringbuffer_write(). Then do prints of n1, n2, cnt2, *rb (yes, the "*" is meant to be there) and src for starters.

It's almost starting to look like the ring buffer object is being corrupted somehow. This should be obvious from the requested print outputs though.

In light of the above output I've had another close look at the 896HD code and found what looks to be a gremlin in the port offset mapping. The effect of this could quite easily be the symptoms you've been describing.

r1782 trunk contains what I hope is a fix to the problem. Would you be able to grab this revision, give it a test and let me know what happens? If it appears to address the problem I'll port it to the 2.0 branch as well.

Having problems compiling from trunk again (Checked out revision 1782):

$ scons PREFIX=/usr DEBUG=yes

scons: *** No SConstruct file found.
File "/usr/lib/scons/SCons/Script/Main.py", line 830, in _main

oops, forgot that I had to go one more directory deep in trunk....

success at 44.1k 48k and 96k. I think you fixed it!

Well, I may have spoken too soon. If I try to stop jackd using qjackctl while at 96k, it freezes and has to be manually killed

More on the new issue of jack freezing when trying to stop jackd via qjackctl:

It will stop cleanly at 44.1k and 48k, but freezes on 88.2k, 96k and 192k

although a simple kill command will kill qjackctl, to actually kill jackd I will have to issue a kill -KILL

This is good news - we're making progress. I assume it's qjackctl which froze in the above tests.

What happens if you run jackd from the command line and kill it using ctrl-C? With trunk it may be instructive to run with "-v 6" rather than "-v 5": the additional messages might be useful in finding the freeze point (assuming it's ffado that's creating the freeze problem).

It might be worthwhile checking the packet sizes at 2x and 4x rates on the 896HD if the above command line test doesn't bear any fruit. I'll do up a patch for this if it proves necessary.

First thing I noticed when I ran at 96000 is that programmable meter 1 is lit up to the red. It did get killed when I did a ctrl-c though.

Thanks for that. Hmm. Perhaps we've got the packet layout slightly wrong for 2x and 4x rates. The crazy meter behaviour tends to suggest that something isn't quite right. The easiest way to resolve that is to find out the size of the packets being sent by the 896HD at those rates.

To this end I have added a simple debug output to the receive side of things (only compile-tested). When the first data packet is received the size of this will be printed in the "-v 6" output. This is in trunk of r1784 (just do a "svn update" from inside your existing libffado/ directory; then scons as per normal). After installing, run this at a 2x rate and find the line which includes "Packet from MOTU: length =" in the output. Let's see what that is and take things from there.

96k

227384470818: Debug (MotuReceiveStreamProcessor.cpp)[ 163] processPacketHeader: Packet from MOTU: length = 840

44.1k

227714516548: Debug (MotuReceiveStreamProcessor.cpp)[ 163] processPacketHeader: Packet from MOTU: length = 424

192k

227844534611: Debug (MotuReceiveStreamProcessor.cpp)[ 163] processPacketHeader: Packet from MOTU: length = 1160

Thanks for this. Based on these numbers, with ADAT turned off (which is your situation) we have 14 channels for 1x rate (which we knew from previous work), 14 channels for a 2x rate and 8 channels (plus some padding) for the 4x rate. This agrees with what FFADO reports for your earlier 2x rate test and, I expect, also agrees with the ports selected by FFADO at 4x rates. So if there's still a MOTU driver issue here I don't think it's due to references beyond the end of the packet data.

Of course just because we have the right packet size doesn't necessarily mean our idea of the location of each channel within the packet is correct. It shouldn't be dramatically wrong though, and in any case should not give rise to shutdown issues.

You mentioned that it (jackd presumedly) did get killed when you did ctrl-C on it. That's interesting; I wonder if a qjackctl update is necessary to run with the latest jackd (although I'm not aware of any incompatibilities). What version of qjackctl is running on your system?

Finally, the programmable meter which lights up at 2x rates: do you happen to know what that's currently set up to meter? That might give us a clue as to what is going full-scale.

Firstly, it seems like they all do it. 1x went to 1, 2x went to 3, and 4x went to 1. I am not exactly aware of how everything works. But my understanding is that one has to manually make connections (which I generally do through qjackctl) so I don't know why Jack would make a connection when I run it from the console. Is there a config file I can delete or change that might be the issue here?

qjackctl is 0.3.4 Build: 2/13/2009 04:11:48 Jack Port aliases support disabled

Sorry, I'm a bit confused here. What do you mean when you say "1x went to 1, 2x went to 3, and 4x went to 1"? What's the "1" and "3" referring to here in particular? Oh hang on, are you saying that meter 1 lit at 1x, meter 3 at 2x and meter 1 at 4x? Do the meters stay lit all the time or do they go out after a while? Do they remain constant or bounce around?

Your understanding is correct about jackd not making connections between jack ports by itself; you do indeed need to have something else make the connections. Are you suspecting auto-connections because of the meter activity? In any case, if there *were* auto connections I would expect it to be the other way around - made by qjackctl and not when starting via a command line.

The version of qjackctl your system has is fairly old - nearly 12 months. A lot has been done with qjackctl in that time - I'll have a quick look and see if there's any reason to suspect that an upgrade might help and advise accordingly. This wouldn't explain the meter issues but may address the apparent freezes when qjackd is used to stop jackd.

When running jackd from the command line, does jackd appear to exit cleanly at all sample rates when ctrl-C is pressed?

The meters stay lit all the time (at least for the short time I ran them). I did not see any jumping between meters either.

I am not sure by what you mean by exit cleanly since I created an interrupt via ctrl-C. There are no rogue versions of jack running after I interrupted it though. I did include a dump at 96k although it looks like it got cut off by this trac program. I could do a quick start and kill at 1x, 2x and 4x and upload a file for each if you wish.

That's interesting about the meters. Do you know what they are currently set up to monitor (since they're programmable on the 896HD as far as I know). At any one time I take it that you're seeing only one meter active though - right?

Ah, writing the above comment just reminded me of something: the trunk of ffado includes a hard-wired 1 kHz test tone at 0dBFS for the MOTU driver (it's present to help evaluate clocking issues). It's hardwired to a set location in the data packet: 6 bytes in from the start of audio data. Based on my current understanding of the port layout in the 896HD packet this would put it in analog-1 for 1x and 2x rates, and analog-3 for 4x rates. Assuming the meters are currently configured to monitor the analog outputs this is probably what you're seeing. The only remaining mystery then would be why it was analog-3 at the 2x rate rather than at the 4x rate as I would expect. Could you perhaps re-test 96k and 192k and see which meter is lit for each of these? In any case that's probably the meter behaviour explained.

By "clean exit" I mean that jackd exits without segfaulting or anything when Ctrl-C is pressed. If it does then at this point I would be inclined to think that the freeze you reported when using qjackctl might be a qjackctl issue. I agree that it seems that Trac truncated your 96 kHz log so the interesting but (the end) wasn't visible. You could get around this by putting the log in as an attachment. Otherwise just post the last 50 or so lines - that should be sufficient to confirm a clean exit.

192k = #3, 96k = #1, 44.1 = #1 so it looks like you may be onto it. I am including the dumps for all three of these as attachments.

ctrl-c at 44.1k

ctrl-c at 96k

ctrl-c at 192k

Thanks for the confirmation of the meter numbers. That pretty much explains that. Note that the test tone is only present for debug levels greater than 5 or 6 (I can't recall which off-hand). So if you run jackd without the post "-dfirewire" "-v ..." option you should find it no longer present. You could also loose the pre "-dfirewire" "-v" option (which switches the jackd core into verbose mode) - we don't really need the higher-level jack debugging output at this stage. Omitting this shouldn't affect the FFADO output from it's "-v" option.

Thanks also for the attachments. According to these attached logs jackd is exitting correctly when you hit ctrl-C from the command line. I'm therefore unsure of what could be causing issues for qjackctl when it's used to shut jackd down. Based on your earlier descriptions it sounds like qjackctl itself is freezing for some reason, perhaps due to a change in the way it has to interact with newer jack releases. However, looking at the qjackctl changelog between 0.3.4 and the current release (0.3.5) I can't see any indication of a need to use 0.3.5 with more recent jack releases, nor do I see anything mentioned which matches the freezes you report. So all in all it's puzzling as to why you're getting the freezes with qjackctl.

It would be good to try to work out what's going on here so we know whether this particular ticket can be closed. So I guess the first thing to do is to re-run jack via qjackctl and then try to stop it. Assuming that qjackctl still freezes (it is qjackctl that's freezing, right?) try to work out whether jackd itself has exitted or what state it's in ("ps auxw" might be helpful for this). The other thing that might be worth trying is to use qjackctl to start jackd using the ALSA backend (I assume you have some form of onboard soundcard using ALSA). Then try shutting that down with qjackctl and see whether the freeze still occurs. This at least will give some indication as to whether the problem is FFADO or exists higher up the chain.

I was starting ffado-mixer and got these error messages (it froze and created a run condition the first time I ran it, but appeared to work fine the second time after I killed the first instance.

hmmm. I tried ALSA and it worked fine. I then went throught the progressions and 44.1, 48, 88.2, and 96 started and stopped fine but 192 froze and I had to manually kill qjackctrl and then do a kill -KILL for jackd.

The main difference is that this jack parameter line was /usr/bin/jackd -R -dfirewire -r192000 -p1024 -n3 (the main difference from before was an additional -p1024 and a -n4, plus a pre -v) I may play around with parameters and see if that makes a difference.

At least some of this appears to be a qjackctl issue as I was able to isolate the issue to when I had the qjackctl messages window open at 96k. It still freezes at 192k regardless of whether the messages window is open or not.

I was starting ffado-mixer and got these error messages ...

Thanks for this. I think I've fixed this in r1785 (coded but not runtime-tested). The problem was simple: the driver doesn't implement level/boost controls for the 896HD (mostly because I've been lead to believe that the interface hardware doesn't support them) but the ffado-mixer was still expecting them. For the moment I've disabled these controls in ffado-mixer, but if it turns out the 896HD does have hardware support for these controls please let me know and I'll activate them.

This is certainly a strange one. Given that jackd stops correctly when run from the command line I'm inclined to think that this might indeed be a qjackctl issue. If your distribution has packaged version 0.3.5 I'd be inclined to upgrade at this point and re-test. Of course it may also be a ffado issue but not specific to the 896HD - only time will tell I guess. The additional command line options you mentioned should not cause the freezing (they should have no dramatic effect at all). For completeness you might like to get qjackctl to do "-n 4" instead of "-n 3" but I'd be surprised if this changed anything.

The other thing I can suggest at this point is to enable verbose ("-v 6") ffado (backend) output from within qjackctl in such a way that you can see the jackd output. Then do the start/stop tests again. Perhaps at "-v 6" level there might be some clue as to where jackd/ffado is getting hung up and we can take a closer look.

Otherwise, perhaps see if there's an Ubuntu qjackctl update available and take it from there. If there isn't we'll have to re-evaluate.

Do you mean the mic/line switch? The 896hd does have that on the rear panel. If it is a software switch you are looking for, I could pop into windows and look at their cuemix software if you tell me what to look for.

These are software switches I'm referring to. If present they would be available for the analog controls and go by names like "boost" and/or "level". They are toggle controls (on/off). On other MOTU interfaces these two controls are mostly applied to line-level inputs; since the 896HD's analog ins all have mic pres (AFAIK) I am fairly sure they won't be present. However, if it's not too much hassle please do check and report back - then we'll know for sure.

Unfortunately the web's not much use for this and the 896HD manual isn't available for download from MOTU :-( so I couldn't find this out for myself.

I compiled and installed qjackctl 3.5 but it did not resolve the messages issue. Since I can't seem to find my original post on the messages issue, I will restate here:

I seem to have isolated the issue to qjackctl's messages window being open when stopping jackd. If I close the messages window, then all but 192k will stop properly. The problem still exists for 192k regardless of the messages window being open or not.

I do have the MOTU manual in front of me and am currently researching....

The manual says that under 4x the 896hd provides 8 channels of analog input and 10 channels of analog output (8 XLR outputs plus stereo headphone out) simultaneously.

So that means that you can include the stereo headphone outputs for the 896HD at 4x!

hmmm, well maybe not. this next paragraph confuses me....

"The headphone output can be assigned to any analog pair or the PHONES setting.... But at the 4x sample rates, the PHONES output is not available from the computer. Instead, it is only available as a destination for the two cuemix DSP mixes. In other words, it can only take cuemix inputs."

So it says that it has a stereo headphone out that you can't use?

Thanks for trying qjackctl 0.3.5. To move forward on the freezes I think we'll have to find a way to make qjackctl insert the "-v 6" after the "-d firewire" option when starting jackd. That way, by viewing the jackd output (if that's possible) we might get a better idea of where jackd/ffado is freezing and therefore where the problem might lie.

That's interesting information about the channels available at 4x rates. What's most interesting about this though is that in terms of the packets coming back from the device at 4x (as we found earlier today) it's only sending 8 channels. At 1x and 2x rates, the spot used in the packet for the headphones send is used for the so-called "mix1" "channel" in the return direction. If MOTU were to send 10 channels to the device I would have expected them to also send 10 channels from the device and include this mix channel at 4x rate. They clearly don't given the packet size coming back from the device.

The other thing to note about this is that the test tone we were talking about earlier shows up as analog-3 at a 4x rate, but as analog-1 on other rates. At 1x and 2x rates the phones sends are in the first two audio channel slots with Analog-1 following at slot 3. The test tone is hardwired to slot 3, so it shows up as analog-1 at 1x and 2x rates - so far so good. At 4x rate the tone is on analog-3, so that means that analog-3 must be at slot 3 when running at 4x rates. This implies that analog-1/2 is at slot 1/2 at 4x rates, displacing the phones send.

Having written the above I then saw your followup, which more or less confirms what I have concluded. At 4x rate there is no separate phones mix sent to the device by the PC. One can still use the phones output by assigning the phones to an analog output pair or by directing a CueMix? bus to them, but you can't send directly to the phones by the PC like you can at 1x and 2x rates. This doesn't surprise me - I'm pretty sure this is the case for all MOTU devices which do 4x rates.

In the "Working with a Mix" section about their cuemix software they have the following:

"* Pan, volume, mute and solo for each input"

Is this the section where we would expect a mention of the "boost" or "level" toggle?

I have to say that the recording is so much smoother with your drivers than the ones in Windows. I would get occasional pops and static running randomly through the 896hd in WinXP. But so far tonight, it was nothing but smoothness....I will see what happens when I add more than 3 tracks... but it didn't take many tracks in windows to make things pretty frustrating.

Regarding boost/level: the boost/level switches - if present - are common to all mixes. That is, they are controls for the physical input rather than having one per control per mix. The pan, volume etc controls have one control per physical input in each individual mix. In contrast there would be only one set of boost/level controls for the entire system.

I've just re-read your previous message where you mentioned the mic/line switch. This is very close conceptually to the "level" switch I'm referring to. Given that the mic/line switch is a hardware switch on the 896HD I'd say that the 896HD doesn't in fact have software controls for boost and/or level and that therefore the fix I applied earlier is correct. However, if you do find mention of these (or any other controls) in the manual which are not present in ffado-mixer, please drop me a line and we'll try to rectify the omission.

I'm happy to hear that things now seem to be running well for you. I'll leave this ticket open for a bit longer to allow us to confirm that the initial issue is well and truly fixed (and to allow us to tie up the last few loose ends). Obviously if you do discover any other issues please do raise further tickets. Alternatively you can always drop a note on the ffado-users or ffado-devel mailing lists, especially if the issue is not easily defined.

A quick note: I'll be travelling over the next week or so for Linux.conf.au. I'll keep an eye on this ticket but might not be able to respond as quickly over that time. Hopefully the problems are behind us. If so, could you confirm at some point so I can close the ticket as fixed?

I'm back online at the conference now. Do you have anything further to add in relation to this ticket? If things appear to work now at 1x and 2x rates then we can probably close it. Please advise.

I have had no issues at 1x and 2x although I haven't pushed it too hard yet. We could probably close it for 1x and 2x. I have been mostly learning my wind synth so I have only done some light recording, but that has been without issue.

Excellent - thanks for the feedback. Certainly the original ffado-mixer bug is now fixed and I'm reasonably confident that the 1x and 2x crashing bug has also been fixed. If the issue reappears please reopen this ticket; alternatively if something else crops up please create a new ticket and we can take things from there.

Thanks again for the initial report and ongoing testing.

After updating to your last fixes for ffado-mixer over svn, I was able to compile and run jack2 (previously I could only get jack1 to work). I did not have the issue of lockup at 192k when stopping jackd via qjackctl with jack2.
