Hi Ken. I do run Lenny as well, but am trying to resolve the realtime problem
on both Etch, and Lenny.
Nigel.
btw: I will check out your blogs.
On Debian Etch, using kernel 2.6.18-5-686, which
I presume is a realtime
one, as when I start jack with qjackctl, and with the realtime box
checked, jack doesn't complain.
Looking at messages though, shows lots of xruns, although no music apps
are being used.
I had this problem on Fedora 7. I'd installed the low latency kernel, and
associated packages from planetccrma, and again jacks messages were
showing lots of xruns. There was an updated pam that came with the kernel
download, which left an /etc/security/limits.conf.rpmnew, and Fernando
suggested adding the changes to the existing file, as the default setup
for
jack-audio-connection-kit in the limits.conf file set rtprio at 20.
That resolved the problem on Fedora 7. No more messages about xruns.
I tried the same few lines, as below, in the limits.conf file in Etch,
but to no success, and there are no default priorities for jack there
anyway.
I advise running sid, or testing, not etch.
My notes from the experience are here:

I've been told that testing is a reasonable alternative to sid, now that it
has usefully-current versions of many of the key audio packages.
