Hi, I test my firewire audio device, M-Audio Firewire Solo and MOTU 828 Mk2 on Ubuntu Studio Marveric Beta. And I found some changes from Marveric.
1. default jackd is version 2. As you know. We can change jackd2 to jackd1 in synaptic exclusively. 2. New firewire stack (?) is default The default kernel modules for firewire is firewire_ohci, firewire_core, crc_itu_t as a result of running "lsmod". In lucid, these are raw1394, ohci1394, ieee1394. The developper of FFADO seem to call the former as "new firewire stack" and latter as "old firewire stack". I read some documents of FFADO and they reccomend to use old firewire stack. But it seems to be old for me. So I test my devices in both stacks. 2. both of my device work but... I can connect jackd2 to my M-Audio FW Solo with both stacks but to 828 Mk2 only with old firewire stack. I use "rmmod" and "modprobe" commands much time in this operation. M-Audio Firewire Solo works fine in both stacks. MOTU 828 Mk2 works in old stack but the sound is the worst. 3. new stack makes more FFADO XRUNs than old stack Then I use Renoise 2.6.6 (Beta) because this version can run under jackd2 in the same device (M-Audio FW Solo). I played the same sample music in both stacks. As a result, I got more FFADO XRUNs than old stack. You can see my report in launchpad. MOTU 828 Mk2 works but the sound is noisy, like buzzing. https://bugs.launchpad.net/ubuntu/+source/libffado/+bug/649542 New firewire stack makes more FFADO XRUNs than old firewire stack. https://bugs.launchpad.net/ubuntu/+source/libffado/+bug/649583 Please post to this mailing list if you know the other changes between lucid and marveric.
