Are you using PulseAudio? It may be that MPD is starting PulseAudio, and because systemd --user daemons run outside the user session you can't access the running PulseAudio from within your session without restarting MPD. If this is the case, I recommend following the instructions at [1] to send the audio from MPD to your user session (ignore the fact that it's written to use different users; it will work fine without that). ~Celti [1]: https://wiki.archlinux.org/index.php/MPD/Tips_and_Tricks#Local_.28with_separate_mpd_user.29
