Sure, you can upgrade the kernel to 2.4. I haven't used Andrew Morton's
low-latency patch before, but I'm currently running the kernel preempt
patch and I like it. I haven't had the time to work on much audio
stuff as of late (trying all those cool programs people suggested is
sitting in my run queue...) but I would suspect that the preempt patch
would do nicely for audio related tasks. My system latency is very
noticably less, even under fairly heavy load (My audio doesn't skip
while: ripping a CD, building a kernel, downloading some goods,
browsing the web with mozilla, and running glxgears at around 150 FPS).
I'd say give it a shot! The procedure is very easy. The preempt patch
is available at kpreempt.sourceforge.net; follow the link to the
latest versions at Robert Love's page. Download a version of the patch
and a matching kernel, apply the patch as you would any kernel patch,
and remember to enable 'preemptable kernel' in General Setup.
