mpd cannot find mixer

[phaoost]

Hello,

I am trying to use mpd, it's playing music, but cannot get control over mixer:

Feb 12 19:52 : mixer: Failed to read mixer for 'My ALSA Device': no such mixer control: PCM

I use following settings in /etc/mpd.conf:

audio_output {
        type            "alsa"
        name            "My ALSA Device"
        device          "hw:0,0"        # optional
        format          "44100:16:2"    # optional
        mixer_device    "default"       # optional
        mixer_control   "PCM"           # optional
        mixer_index     "0"             # optional
}

I tried to modify default settings for mixer with no luck. Can someone let me know how to discover proper values?
