i have yet add my user to audio group and i have modify
/etc/security/limits.conf too as it is explained in this page
(http://www.linuxquestions.org/questions/showthread.php?t=386921 )
my problems are not in recording audio or playing external midi
equipment but in playing soft-synth. for example if run the 3rd patch of
hexter (FatThinE.P.) at 32notes of poliphony or the patch "The master"
of LMMS i got a lot of xrun.
where can i download the -ck patchset?
thank you a lot.

should work at low latency.
so i would like to recompile my kernel multimedia with ingo molnar's patch.
is it possible to apply the patch to mandriva's kernel or i must
recompile an official kernel from kernel.org?
is ingo molnar's patch the only step i have to take to have a
low-latency kernel?
thank you
bye

Ingo's patch works well for me. I have my doubts that you could
successfully apply his patch to the default Mandrake kernel. You could
try the -ck patchset, as IIRC, that's the one that Studio To Go! uses
and I assume it has Ingo's patch as part of it.
When to configure the kernel, you'll want the option "Complete Preemption."

I'd go with the precompiled multimedia kernel.
I have an audiophile2496 as well and my AMD 2000+ has no problem with
low latency.
The trick though is to add yourself to the "audio" group.
As you can see in /etc/security/limits.conf those members have
realtime capabilities.
