If I vary that channel in alsamixer I get no variation in volume. If I vary the PCM channel instead I get the desired effect that volume buttons should have. Since pulseaudio varies the Master channel by default and does not respect any configuration settings telling it to use other settings, I suggest swapping these two channels so that pulseaudio works out of the box.
