    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]

    regards,
