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

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 ======================================================================= $ cat /etc/security/limits.d/audio.conf @audio - rtprio 99 @audio - memlock unlimited #@audio - nice -19 ======================================================================= jack sais: $ jackd -v -d firewire [...] new client: firewire_pcm, id = 1 type 1 @ 0x85cf120 fd = -1 new buffer size 1024 01651166042: (ffado.cpp)[ 92] ffado_streaming_init: libffado 2.999.0- built Aug 11 2010 00:12:04 firewire ERR: Error creating FFADO streaming device cannot load driver module firewire starting server engine shutdown [...] ======================================================================= $ ffado-test ListDevices ----------------------------------------------- FFADO test and diagnostic utility Part of the FFADO project -- www.ffado.org Version: 2.999.0- (C) 2008, Daniel Wagner, Pieter Palmers This program comes with ABSOLUTELY NO WARRANTY. ----------------------------------------------- === 1394 PORT 0 === Node id GUID VendorId ModelId Vendor - Model 0 0x000acd120070008a 0x00000ACD 0x00000000 Linux - ohci1394 - 1 0x0040ab0000c24d8b 0x000040AB 0x00010048 EDIROL - EDIROL FA-101 no message buffer overruns ======================================================================= ffado-test-streaming ffado_streaming_wait ============================================ Xruns: 0 ============================================ ---------------------------------------------------- Dumping StreamProcessorManager information...
