Thanks for the investigation.

The only change I needed to do was add 
"/run/user/1000/pulse/native" (obtained from pactl info | grep 
'Server String'). I believe it may be because mpd was connecting 
or trying to connect to different server (I also noticed 
"shm_unlink(/pulse-shm-2228832221) failed: No such file or 
directory" in the logs and thought something wrong with 
auto-detection of mpd).
