Looks like that in my case the cause of the issue was an attempt to make pulseaudio control PCM volume instead if it's weird way to control both master and PCM volume. I had 'load-module module-alsa-sink control=PCM' in default.pa for this and removing it seems to solve the problem (although now I have weird behaving volume controls again).
