Thank you for the reply.  There are security risks running pulseaudio
in system mode[1].  I can append use PAMName=login and
After=systemd-user-sessions.service, but doing so moves the service
out of the system slice into the user slice.  Once in the user slice,
when called to reboot or shutdown, systemd brutally kills it before it
can gracefully stop which causes data loss as documented in my
previous thread[2].

Is there solution that keeps the service under the user slice and
allows systemd to wait for it to shutdown before killing on on a
system reboot/shutdown?
