Hi! I've just upgraded from 7.1-PRERELEASE to 7.1-STABLE via source upgrade and divcovered that my sound stopped working. I was aware about recent HDA driver update and tried to switch hw.snd.default_unit back and forth but that did not help. Finally I've realised that's just mixer values changed their meaning: now I can't hear anything at levels 50:50 of both 'mixer pcm' and 'mixer vol' and have to increase values significantly to make sound: upto 85:85 of both. Isn't it a bug?
