It seems to work, although now I'm getting the problem I had in the very
beginning, that is that when I mute the sound (or put it lower than the
maximum volume), it keeps getting louder (yes, even when muted!). It helps
just to use the 'Front' volume switch instead of the 'Main' one, just the
way the module-assistant fix handled it (it attached the hardware volume
controls to the 'Front' slider).
