I'm having really bad xrun problems in jack with my MAudio 24/96 card. I
can't find any setting that doesn't result in 10's of xruns every few
minutes which is obviously unacceptable. The latency doc in the linux
audio users page at
http://www.djcj.org/LAU/guide/Low_latency-Mini-HOWTO.php3 points out that
most soundcards want to have an IRQ of 9, 10 or 11. When I cat
/proc/interrupts (below), it appears that my card is at IRQ 19 which as I
understand it puts it behind just about everything. Could that
be the root of my xrun problem? If so, how can I make the card be on
another interrupt.
Regards,
Bill
