Hi there, I have ut2003/2004, and in both I can hear the crackling with kernel 2.6.3. With 2.6.2-rc3 everything was fine. I tried another openal lib (selfcompiled, armyops) but it doesn't help. (I normally start my ut with "nice -n -1". If I start it with normal priority, the sound gets a bit less crackling) xmms works fine. I have an intel8x0 alsa driver with oss support for my SiS chip (P4 2.4Ghz/SiS645DX). And I'm using the nvidia driver for my GF card. Kernel compiled with PREEMPT.
