I see 2.6.32 here. Make sure to have libraw1394-2.0.5 installed.

Should be ok: libraw1394-11 2.0.5-1 installed


jo...@auryn:~$ jackd -dfirewire -r44100 -n10 -p 2048 -v2

IIRC, the FA-66 has a manual samplerate switch? Make sure it matches
what you specify for jackd.

I am aware of that - and misconfiguration there leads to other error. But thanks for pointing it out anyway!


Also: -n10 clearly is too much, best is to omit -n completely. -p 2048 is also rather high, neglect it or set it to 512.

Finding the right value(s) for p (and n) could be a hard job, so playing with those might be useful.

I started with relying on defaults - setting them higher was out of desparation, after noticing some other advice saying that this particular error could be due to too _low_ values for these.

Are you suggesting to shoot in the dark for magic combinations here, and that _both_ too low and too high values lead to same error messages?


Also make sure to powercycle your FA-66 between failing runs, otherwise, the device could be left in some locked-up state.

Thanks for mentioning. I did powercycle between some of the attempts but not all - will do it consistently from now on (although I suspect that the box hanging leads to other errors, at least they did in the past with freebob).


Cannot switch to ePS_DryRunning from ePS_WaitingForStream

This basically means that FFADO cannot start the streaming engine.
Unfortunately, there are many reaons causing this error:

 * old firmware (depending on the device, but yours probably is fine)

 * new Juju firewire stack and libraw1394 < 2.0.5

 * device in lock state from previous runs

 * crappy firewire host controllers, you could check
   http://subversion.ffado.org/wiki/HostControllers

 * something else


I don't believe there's something wrong with the FFADO or jackd packages in Debian, it's just the usual trouble with FFADO.

Thanks for the pointers.  I'll try some more.


You could join the FFADO user mailing list and ask for help.


In any case, let me (and this bug) know if something works for you...

I will.


 - Jonas
