A friend of mine has just installed ubuntu with a

1) Add him to the audio group /etc/udev/rules.d/40-permissions.rules
2) Add the following to
KERNEL=="raw1394", GROUP="audio"
KERNEL=="dv1394*", GROUP="audio"
KERNEL=="video1394*", GROUP="audio"
3) Install a realtime kernel
However he still reports that jack exits after about 10s with
buffersize 128 and he get's lots of xruns on larger buffer settings (I
think even on 1024).
This surprises me, since I run standard ubuntu (recently installed the
realtime kernel, though) with no xruns on buffersize 128 with an FA66.
Is there anything I forgot in my over-the-phone instructions? Other
ideas on how to narrow this down?
NB: I don't his computer, but according to him, it's an "old
laptop"...
I had to set periods/buffer to 3 on my laptop (the default was 2). I
don't think jack exited when I had the default setting on, but it got
lots of xruns and playback was *really* rough.
HTH,
