High pitch noises on ens1371 with alsa

Hello I have some really trouble with alsa and arch. I've been on this a week! The sound makes high pitch noises (crackling?) ! Especially when I load the cpu (like changing programs, compiling, page up and down in browser).

First I thought it was the card itself that was the source, so I switched in another one, an external USB soundcard. It got sound, but this card stutters instead of making high pitch sounds. Then I just for fun tried in an Ubuntu live CD, there it worked PERFECT, on both cards as it should, no high pitch sound nor stuttering.

Then I thought maybe it is that the kernel has low latency preemptive kernel, so I made my own with voluntary preemptive. No difference. I've also tried making my own .asoundrc and setting up the buffer time, and using dmix...

I've tried to playback mp3, ogg, different video formats etc. in all sorts of programs. Even alsaplayer, both through oss emulation and alsa. The problem was there on 2.6.22 as well as 2.6.23, before that I didn't use Arch so I dunno there. My soundcard is Ensoniq ES1371 [AudioPCI-97]. And my sound related modules are (without the USB card)...

Please anybody? I want to use Arch, but the noises makes the music so annoying that I can't listen to it, and I am addicted to music...
