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]
