[LAU] ubuntu lucid, ffado, firewire, jackd problems

[Luka Princic // Nova deViator]

hi everyone,

this one is a bit on the border between LAD and LAU, but i was hoping
somebody would help pointing me to the right direction...

i've installed new Ubuntu Lucid in june and didn't really check if my
Edirol FA-101 still works with it. now i checked it (a week before a
performance, haha) and it has problems - of course. after loads of
reading wikis and forums online i'm still failing although i'm almost
there. it seems the problem is the new kernel (>=2.6.32) that is
including new firewire stack (called 'juju'?). seems like ffado
(firewire audio 'library/driver') 2.0.0 is unable to talk to this new
stack. at the moment there are two directions to go - either stick with
older (-rt) kernel (i tried linux-image-2.6.31-11-rt) and ffado should
work as well as jack, or go ahead and try newer kernels with that new fw
(juju) stack, ffado 2.0.1 and libraw1394 2.0.5.

i have come very close to running it, but it stops with jack not
cooperating. ffado-test-streaming manages to talk to the device and
streames data to and from and shows all 10 ins and outs!

i was affraid to install jackd2 from maverick as that would upgrade a
lot of packages - effectively start an upgrade to Maverick Alpha...

please help. i'm somewhat desperate because of coming performance on
thursday.

here's what i have:
- basic system is lucid, but now with maverick repos (for newer
libraw1394 and ffado)
- running kernel linux-image-2.6.32-24-generic-pae (from lucid)
- libffado2 2.0.1+svn1856-1ubuntu1
- libraw1394-11 2.0.5-2ubuntu1
- chmod 777 /dev/raw1394
