I am having trouble with the output channels being assigned correctly for my
hardware. I have searched and cannot see anything similar. It seems the
channels are reported incorrectly and I actually have no master volume. My
main problem is that when I am using head phones I can adjust the volume
using my normal KDE controls, multimedia keys. When I unplug the head phones
only the PCM volume control affects the volume, otherwise I get the highest
volume from the internal speakers. See info below:

I have tried ac97_quirk with no setting, =1 and =2. Here are the results of
adjusting the output levels. Not that "headphone" indicates the head phones
were plugged into the jack, "no headphone" indicates the head phones were not
plugged into the jack and output is to the internal speakers. The first entry
is the output level name and the second is what it is actually adjusting.
Note that I don't have surround sound so the 3D levels are somewhat
uninteresting.
