Audio Output

MPD supports various audio output types, as well as playing through multiple

audio outputs at the same time, through multiple audio_output settings

blocks. Setting this block is optional, though the server will only attempt

autodetection for one sound card.

See http://mpd.wikia.com/wiki/Configuration#Audio_Outputs for examples of

other audio outputs.

An example of an ALSA output:

audio_output {
type "alsa"
name "NuForce uDAC"
device "hw:1,0" # optional

format "44100:16:2" # optional

mixer_type "hardware" # optional

mixer_device "default" # optional

mixer_control "PCM" # optional

mixer_index "0" # optional

}
