[linux-audio-user] Weird sounds

[Vi]

Hi, I'm using alsa with via82xx configured. And sometimes when I play 
sound with xmms, xine, etc. I get wierd noise
on background (popping sound). When I go to alsamixer and change via dxs 
(even very litle) the sound desapears,
but backround popping stays. If I'm changing pcm, it becomes more 
silent, but when I'm turning my speakers louder
I still hear popping noise. The thing is that it's not happening always, 
but in 50% of cases. And there is no such problem
under windows (so it's not the speakers who are guilty). I'm confused 
about this stuff. Please help.

Thanks.
