Are you trying to run PulseAudio as a user service or as a system
service?

When running as a user service, you shouldn't try to use systemd to
manage pulseaudio, because PulseAudio can't find the session bus when
started by systemd, and that can cause libdbus to complain about unset
DISPLAY. PulseAudio itself doesn't care about DISPLAY unless you
specifically try to load the x11 specific modules.

You didn't give much details, but I'm guessing that you're trying to use
PulseAudio as a system service, but you don't pass the --system command
line parameter, so PulseAudio thinks that it's supposed to be a user
service.
