[Voyage-linux] Repeated "clicks" in audio output from MPD

[Kim-man 'Punky' TSE]

Hi Patrick,

Remove the line "format          "44100:16:2" in ALSA configuration of /etc/mpd.conf.  Restart mpd and see how it goes.

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
}

Regards,
