Thanks for the interest Daniel.

Yes, it makes sense that it doesn't occur for all users snd-intel8x0 as
the module seems to be used for a wide range of cards.

I see from some searching that people are doing all sorts of ac97_quirk
options, like 3 and 7 and 0 and 1, etc. Not sure what each do at the
moment, but ac97_quirk=1 definitely fixes the volume control for my SiS
audio controller.

If you need it, there is output from "lspci -vv" on my card located here
(at the bottom):

Any other info needed?
