About two weeks ago, I purchased the above-mentioned firewire interface, based on it's 'supported' status on the ffado website, and positive experiences reported on this list. I've been able to access it from windows XP using the saffire control app, and have made recordings using Reaper in that environment. However, my attempts to get it running under Linux have gotten essentially nowhere. Based on HOWTO's I found on the Ubuntu forum and the FFADO wiki, I have compiled locally the latest beta6 of ffado, and the latest svn checkout of jackd. After resolving some permission problems, I have gotten the driver to load, but even with no DAW yet started, jackd is reporting xruns, and after the fourth 'xrun callback' message, jackd stops. Is there someone here willing to work with me to get this up and running?

I'm starting it with jackctl, here's the command line that it appears to have generated: /usr/bin/jackd -R -P89 -dfirewire -r44100 -p1024 -n3 (My entire jackd log is posted as an attachment to ticked #140 on the ffado.org tracker) The laptop's built-in firewire port usesa VIA controller. Also on that ticket are posted the output of lshw and ffado-diag on my system. I also have a firewire-equipped desktop, but that box is currently running without a gui and only 256M of RAM. When my newegg order arrives, I'll certainly give it a try there as well. -- Rick Green "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." -Benjamin Franklin
