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.
