Hi,
after I upgraded from 2.6.34-rc5-mm1 to 2.6.35-rc5-mm1 (there were other issues in between them), the sound from my soundcard is very very quiet.

Any ideas?
I've just find out that whatever value 1-64 is set the Master control to via amixer, it plays still the same. So the mixer (Master volume) is somehow screwed up.
These two are the same volumes: # amixer -D hw sset Master,0 64 Simple mixer control 'Master',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum Playback channels: Mono Limits: Playback 0 - 64 Mono: Playback 64 [100%] [0.00dB] [on] # amixer -D hw sset Master,0 1 Simple mixer control 'Master',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum Playback channels: Mono Limits: Playback 0 - 64 Mono: Playback 1 [2%] [-47.25dB] [on]
This turns sound off, indeed: amixer -D hw sset Master,0 0 Simple mixer control 'Master',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum Playback channels: Mono Limits: Playback 0 - 64 Mono: Playback 0 [0%] [-48.00dB] [on]
