What I am intending to do is to setup MPD "dedicated" server.
Edit /etc/mpd (pipewire) Fedora 34 and later
audio_output { type "pipewire" name "PipeWire" }
Edit /etc/mpd (pulseaudio)
audio_output { type "pulse" name "Aerion Pulse Daemon" device "hw:0,0" format "44100:16:2" }
Edit /etc/init.d/mpd and add next line:
/usr/bin/pulseaudio --start --log-target=syslog & between lines: {{{ /usr/bin/pulseaudio --start --log-target=syslog &daemon $mpd }}}
Edit /etc/pulse/default.pa file and add after the last line:
load-module module-native-protocol-tcp listen=0.0.0.0 auth-anonymous=1
