According to the wiki of ArchLinux, users of PulseAudio with a
system-wide MPD configuration have to implement a workaground:

<https://wiki.archlinux.org/index.php/Music_Player_Daemon/Tips_and_tricks#Local_.28with_separate_mpd_user.29>

It suggests letting mpd use pulseaudio's tcp module to send sound to
localhost, where user's pulseaudio server listening.

This seems too tricky for me, I'll suggest you forget the system herd
service, and launch mpd as a normal user:
