I confirm what Jimmy Buck already said: when you shutdown your system in a forced way (or if it crashes, as it was in my case), the sound is not muted after a reboot. It looks like something mutes the channels upon shutdown, and then re-mutes them upon login. That's why the master channel is unmuted after boot, but gets muted at login.
