I seem to remember (I had this problem before) that pulseaudio by
default applies mixing to a greater than stereo card if a stereo sample
is sent to it. At the time there was a flag or option in the config
file that could be set, but since I didn't end up going that route I
don't have it anymore. I believe it was Lennart who gave me the hint to
the issue (and might have actually fixed my specific issue in the
code). This was back in 9.10, which I am still running.<br>

Just another avenue to explore, sometimes that's all you need.<br>

I had that magic option in my previous mainboard, but apparently
this one does not have it (see the attached output of "amixer -D hw:0").

Yeah I figured that each channel may have independent hardware volume
control, which would have caused this kind of setup but I guess that was
a dead end :(
I've not got any ideas on this I'm afraid but perhaps some other folks
on the list do.
