Hi I went ahead and got myself a edirol fa-66. Having no experience with firewire I have no idea why it doesn't work. The problem is that jack (qjackctl) seems to start up fine, but dies after a few seconds. My jack settings are IMO conservative: buffer size of 256. Here's what's printed in "messages": 19:39:10.306 Patchbay activated. 19:39:10.354 Statistics reset. 19:39:10.364 Startup script... 19:39:10.365 artsshell -q terminate 19:39:10.403 ALSA connection graph change. 19:39:10.787 Startup script terminated with exit status=256. 19:39:10.788 JACK is starting... 19:39:10.788 /usr/bin/jackd -R -P80 -m -dfreebob -dhw:0 -r48000 -p128 -n3 -D 19:39:10.790 JACK was started with PID=10604. jackd 0.109.2 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. loading driver ..
