Probably. Adding "control=" fixed the problem and sound is back on.

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.
