[linux-audio-user] jack and Edirol UA-1A USB soundcard

Hi

I'm trying to get jack running with my Edirol UA-1A USB soundcard. The
card works well with alsa (so no jack) but my system freezes after a
while (often when a client, fx xmms or ams) disconnects. Anybody has a
clue how to proceed or what could be wrong?

Here's some hopefully relevant info:

atte@email-addr-hidden:~$ cat .jackdrc
/usr/bin/jackd -R -dalsa -dhw:1 -r44100 -p256 -n3

atte@email-addr-hidden:~$ cat /proc/asound/cards
0 [SI7012 ]: ICH - SiS SI7012
                      SiS SI7012 with ALC200,200P at 0xdc00, irq 10

                      Roland EDIROL UA-1A at usb-0000:00:03.1-2, full speed
