I have a STAC9220 codec and I noticed that during boot it calls for soft
pcm volume. Does this only apply to the pcm knob? I know for a fact there
is an outamp on nid 11 that controls the master volume. I can't tell what
nids are assigned to which volume controls from the dmesg. Both pcm and
master volume "work", but not as I would expect. Going from 100 to 50 is
definitely not half volume on either control. I can't remember if the HDA
spec sets the gain by dB or not, which might make the response
logarithmic, but when I was toying with the other driver it seemed to give
more natural results.
Anyway, my dmesg is below. You can see nid 11 is fed by nid 7 which is fed
by nid 2, so nid 11 essentially has the output gain for that DAC.
