OK. The problem is that the card has a 6-channel Master control that
alsamixer converts into three controls, including "Master Front" that
confused us. Unfortunately, PulseAudio cannot handle such controls.
There is a FIXME about this:

Thanks for the pointer to the source code! I was able to get this to
work by applying this extremely dumb patch:

Seems to work OK. The hardware volumes are now adjusted correctly.
I should mention that all 8 mixer channels are working (the PA slider
controls all the 5 "Master" sliders in alsamixer), even though the code
suggests that only the first two channels should be working. I'm not
sure why that is, but it means that it works correctly even when having
more that two speakers connected.
