Description

I'm running the RC1 version on Ubuntustudio 8.04. Last night I recorded a show using the eight built-in preamps, and one outboard ADAT unit. Unfortunately, I was never able to capture any audio thru the ADAT channels 11-15. Since I was running FOH as well, I could not divert my attention to do any debugging during the show.

This morning, I duplicated the setup back at home, and discovered what

was happening:

I had a single ADAT interface plugged into the 'ADAT 9-16 in' port, and

I was trying to capture audio from channels 11-15, which correspond to ADAT channels 1-5. Doh!

But the confusing part was that I had used ffado-mixer-qt3 to set the

clock sync source to 'ADAT 1', and it sync'd up fine.

This morning, I set up the rig with the ADAT interface plugged into

'ADAT 1-8 in', and I get audio streamed from channels 11-15 just fine, but in order to get the clock source to sync up, I have to select 'ADAT 2' as the clock source.

So it appears that in the RC1 version, the clock source selection is

actually reversed from what it should be. I see a note in the beta7 - RC1 release notes that clock source selection was corrected, but no notes in the RC1 - RC2 release pertaining to this issue, and a search of this list archive didn't turn up a comment, so I thought I'd mention it.
