It is not a runtime dependency. Scons 2 is currently 119 used to build FFADO. Work continues on making FFADO's scons scripts 120 compatible with both scons 2 and 3. Testing and bug reports when using 121 scons 3 are welcomed. 122 117 123 To build libffado you need several libraries. For all libraries a 118 124 version is provided which is a 'known good' version. The first few … … 135 141 While jack1 0.109.12 will work, jack1 >= 0.122.0 or jack2 >= 1.9.9 are 136 142 recommended if support for jack's setbufsize functionality is desired. 137 [NOTE: at the time of writing, jack1 0.122.0 and jack2 1.9.9 are the138 development (SVN) versions.]139 143 140 144 Optionally, but recommended is that you install qjackctl: … … 238 242 ------------------- 239 243 240 First of all, check whether your problem is in fact a problem, and whether 241 it is a FFADO problem. The magic tool for this is google. 244 First of all, check whether your problem is a known issue, and whether 245 it is a FFADO problem. Use your chosen web search engine for this. 246 247 Many distributor kernels now include the alternative ALSA audio streaming 248 drivers for selected firewire audio interfaces (snd-bebob, snd-dice, etc). 249 These are developed independently of FFADO. If these kernel modules are 250 loaded then FFADO's streaming engine cannot be used: using jackd's 251 "firewire" driver will fail because the kernel drivers have ownership of the 252 interface. To continue to use FFADO's streaming system, the applicable 253 snd-* module must be unloaded from the kernel and prevented from loading on 254 boot. Use "rmmod" to remove the module from the running system, and 255 blacklist the relevant snd-* module in a file under /lib/modprobe.d/ (or 256 your distribution's equivalent). 242 257 243 258 When seeking support from the developers keep in mind that none of the FFADO … … 248 263 * http://www.ffado.org/ 249 264 * http://subversion.ffado.org/ 250 * http://www.google.com/265 * your chosen search engine 251 266 (the terms "ffado-devel" and "ffado-user" work well) 252 267 … … 280 295 281 296 The distribution contains a tool to gather some information about your 282 system. you can run it as follows: 297 system. When FFADO is installed on the system it can be run directly: 298 299 $ ffado-diag > ffado-diag.log 300 301 It is also possible to run it from the source tree: 283 302 284 303 $ cd support/tools
