Configuring MPD audio_output on Allwinner A20 (BananaPi M1)

[SomeArmbianForumUser]

MPD as installed by Armbian needs this audio_output configuration in /etc/mpd.conf in order to use the volume control of the on-board sound with Armbian mainline kernel 5.x on the BananaPi M1 (and maybe other A20 boards):

audio_output {
    type        "alsa"
    name        "BananaPi BuiltIn"
    device        "hw:0,0"
    mixer_type      "hardware"
    mixer_device    "default"
    mixer_control    "Power Amplifier"
}
