mpd don't work with pipewire(system-wide)

[luffby]

Hello,
I'm using mpd as systemd service, and pipewire as user service.
In ncmpc track is forever paused.

So, journalctl -b | grep mpd

Aug 04 16:43:04 archpc systemd[1]: Listening on mpd.socket.

Thanks in advance

ps -e -o ruser -o euser -o cmd | grep -E "mpd|pipewire|wireplumber" (if it helps somehow)

RUSER EUSER COMMAND
trashy trashy /usr/bin/pipewire
trashy trashy /usr/bin/wireplumber
mpd mpd /usr/bin/mpd --systemd

Is what you're trying to do even possible with PipeWire? This is a PipeWire-specific problem, not a MPD-specific problem. I can't help with PipeWire because I've never used it.
