[linux-audio-user] Which kernel for low latency?

I've been using a 2.4.2 kernel with Andrew Morton's patches and I got 
jack to work very well. However, seeing 2.6 is the latest and greatest 
I'd like to switch but am having no luck thus far.

Q. If anyone has got jack to work great with a 2.6(.1) kernel could you 
share with me what version of the 2.6 kernel you used and what patches 
(if any)

At the moment I'm trying a 2.6.1 with an mm4 patch but I'm getting no 
sound with my soundblaster live.
I've done:
       <*> Sound card support

and, under Advanced Linux Sound Architecture --->

       <*> Advanced Linux Sound Architecture
       <*> Sequencer support
       <*> OSS API emulation
       <*> OSS Mixer API
       <*> OSS PCM (digital audio) API
       <*> OSS Sequencer API

rebooted and install alsa-lib-1.0.1 and alsa-utils-1.0.1 as well but I 
get these errors

root at upstairs glenn # aplay /usr/kde/3.2/share/sounds/pop.wav
ALSA lib pcm_hw.c:1055:(snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed: 
No such file or directory
aplay: main:502: audio open error: No such file or directory


glenn at upstairs glenn $ alsamixer
No mixer elems found

I'm at a loss but am interested at what type of kernel others are using. 
I think my next best bet is to remove alsa from the kernel and install 
it seperately.
