I know. Although I don't think that the mixer settings are the problem
because I tried tweaking every single one of them without getting any
audio out. Also, after a "killall pulseaudio", mplayer happily plays
sound through the card.
That might be because PA enables a path that makes no sense on your
card.
Probably. Adding "control=" fixed the problem and sound is back on.
Please do the following:
run mplayer so that it properly produces audio and bypasses PA. Then
do an "amixer -c0> a". Then, run PA and run mplayer on top of it and
verify with pavucontrol that you are playing audio on the right device
and make sure that PA at least "thinks" it plays something. Then,
do an "amixer -c0> b".
Finally, do a "diff -u a b -C 7" and paste that here.
diff: conflicting output style options
Here's "diff -U 5 a b"

Apparently, PulseAudio mutes the "Multi Track Peak" control. I did not
catch this earlier, since that channel appear "frozen" in the alsamixer UI.
Anyhow, the problem appears fixed for me now, but if I can provide more
info that will help others with the same card, please tell me how.
Regards,
David
