That's along the line of what I'm thinking, but I don't know how to fix it.

All you said make sense, and you guessed right with XMMS. Output to ESD or OSS 
gives me static.

Yep, aggreed, true. I know and have tried both alsamixer and aumix (the 
gnome-volume-control and kmix is just the 'fancy' GUI).

Yep, correct. As far as I know, all the necessary module is loaded. Still, no 
luck with OSS emulation. Here is what I think the pertinent lsmod output:

# lsmod | grep snd
snd_pcm_oss            40740  0 
snd_mixer_oss          13824  1 snd_pcm_oss
snd_via82xx            19104  1 
snd_pcm                68872  2 snd_pcm_oss,snd_via82xx
snd_timer              17156  1 snd_pcm
snd_ac97_codec         50436  1 snd_via82xx
snd_page_alloc          7940  2 snd_via82xx,snd_pcm
gameport                3328  1 snd_via82xx
snd_mpu401_uart         4864  1 snd_via82xx
snd_rawmidi            17184  1 snd_mpu401_uart
snd_seq_device          6152  1 snd_rawmidi
snd                    38372  11 
snd_pcm_oss,snd_mixer_oss,snd_via82xx,snd_pcm,snd_timer,snd_ac97_codec,snd_mpu401_uart,snd_rawmidi,snd_seq_device
soundcore               6112  1 snd

So, that's all the troubleshooting background. Any idea on the solution ? Does 
anyone else experience this with the same soundcard / chipset? 

Thanks a lot for the respond.
