I'm currently setting up an audio system on Debian sarge.
The system will be used for audio work only.
My sound hardware is RME Multiface and the PCI card.
Of course I want ALSA and JACK.
I wonder which kernel version I should try first, 2.4.?? (which one)
or a 2.6.0 test kernel? I'm fine with kernel source from kernel.org
and don't need a debianised kernel source.
Please let me know which patches are needed (like lowlat, preemt)
for the kernel version in question, as this is not clear to me.
I know this question shows that I'm not very well informed about
the different kernels, but I *do* like learning ;-)
Thanks a lot for your help!

kernel-source-2.4.21 is the latest available in Debian unstable, so you could just get
that one, as well as alsa-source, kernel-patch-2.4-lowlatency, kernel-patch-2.4-preempt.
You probably also want to apply the capability patch (manually, see jack docs @
jackit.sf.net). I think this is the kernel setup that most people use.
For the 2.6.0-test series, you should get the latest from kernel.org, since the Debian
packackes are some weeks behind.

Thank you for the information. I'll try that out now...
BTW: I was just compiling a 2.4.22 (unpatched) just before I got your
answer ;-) So I'll have both of them to try out (at least if nobody
tells me now, it is not worth bothering about one of them...)
BTW: I'd appreciate if someone would answer the question of
Luis Pablo about low latency and 2.4.22
For the 2.6.0-test series, you should get the latest
from kernel.org,
sure...
How usable is it currently for audio?
Which patches?
Thanks a lot for sharing infos and experience, Robert.

I run 2.6.0-test3 and it works quite well, although I never tried any
patched 2.4.x kernel, so I don't have a lot to compare with. I didn't
apply any patches, just selected "pre-emptive-kernel" in the
configuration. Without X I'm able to run csound with a buffersize of 64
on a medium complex analog style patch and too much polyphony to count
(P4 2400 laptop, using the buildin intel i810 soundcard).
But I'm also interrested in meassuring the performance of my system
including latency more precisely. Is there software outthere that will
to it for me in an accurate way? Are there any patches that can be
applied to the 2.6.0 kernels to improve latency?
