Sorry for replying to my previous reply with everything now snipped.
I've downloaded, and installed kernel 2.6.21rt4, 2.6.21.5rt18, and rtirq, but
am still getting xruns when starting jackd in qjackctl. An xrun about every 3
secs, and that's with no music apps being used.
Is there anything else I need to do to get zero xruns when starting jackd?
Do I need to edit /etc/security/limits.conf for example, as I had to do for
Fedora 7? As default this file has everything commented out in Etch, but this
file in Fedora 7 already had some lines for jack-audio-connection-kit set up
as default, but only with a rtprio of 20. The updated pam that came down when
installing the planetccrma low latency kernel, left a limits.conf.rpmnew with
higher priorities. I added these to the existing limits.conf file, commenting
out the defaults, and now when starting jack on Fedora 7, I have zero xruns.
I still get the odd xrun when running a music app, but nothing when jack is
started with no music apps being used. I've put a bit of jack's messages
output below.
