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:

http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/alsa-mixer.c#n1603

To Clemens Ladisch: sorry for falsely blaming you about this bug.

To Nikos Chantziaras: until this is fixed, you'll have to live with
software volume control. To make the desired hardware Master volume
persist across reboots, please follow these two steps.

1. alsamixer -c0, set it to the desired level.
2. sudo alsactl store
