Default Sound: Center and Subwoofer don't work


I have an NForce2 mainboard and this soundstorm-Sound. I think its called AC97.

With the module that is in the kernel (snd_intel_8x0) i have only front 2 speakers working. If i do "duplicate front" in alsamixer i hear the rear ones too. No subwoofer and no center speaker working.

If i boot windows everything works fine, so the hardware is not damaged or broken.

Then, i downloaded the newest Nvidia driver. I installed and loaded the nvsound module. Well, now 4 speakers are working. No subwoofer, no center again.

I played around with alsamixer and nvmixer for days. No result.
What am i doing wrong?

I have Debian (Sid) Linux. I tried different kernels: 2.6.8, 2.6.9 and today I compiled all the alsa stuff as modules, and the OSS emulation stuff. But i did not compile OSS at all. Did i do anything wrong?
