Subject: [linux-audio-user] xruns, ksoftirqd, alsa, jack

Hello all,
I have the following set up:

1.8Ghz CPU
512 RAM
VXPocket 440 (Digigram)
kernel with low latency patch applied
Planet CCRMA software installed

When I fire up jack, I get xruns. At the same time, the ksoftirqd grabs about
50% of the CPU. Is this normal?

I've tried tuning the jackd settings, and the only thing that seems to work is
-C (capture only) but that seems fairly unproductive in a real multitrack
recording situation.

Any suggestions?

Thanks!
Wade
