Possible snd-intel8x0 bug

Possible snd-intel8x0 bug

[Lisandro Pin]

  Hello. I have alsa running on a ECS K7S5A motherboard, which is listed to 
have a C-Media CMI9738 onboard audio chip, with a SIS chipset. It appears as 
  a "SiS SiS7012 PCI Audio Accelerator (rev 160)" on /proc/pci.

  The thing is, the snd-intel8x0 driver works great here... except for the 
PCM output volume. It can't be changed from either alsamixer or any OSS 
based mixer; it's on for every single position of the fader and off if it's 
set to zero. Any other mixer control works right. I've been trying to fix 
this myself for a while now (beleiving it was a dumb mistake of my part), 
but now i know of another person that has the same issue with that 
particular chip.

  Lys.

IIRC, CMIPCI AC97 codec chips has *NO* PCM volume controls...
so it's not a bug.
