Thanks Roman. Reading the patch description I am not 100% sure whether this patch will fix my 
problem or not. Any chances this patch will show up in PSB?

Another thing I notcied is that if I launch alsamixer then:
- default card is labeled as PulseAudio and the volume slider works correctly (unlike in KMix)
- I can switch to HD-Audio Generic card and all the sliders work as expected
- If I switch to HDA Nvidia card then all the switch are labeled as SPDIF switches, which explains 
why they don't do anything - I'm not using SPDIF.
