[pulseaudio-discuss] Help needed configuring Bluetooth speaker with system mode

Okay, here¹s a follow-up.  Still no joy.

I managed to get PulseAudio to run logged in as a regular user.  I had to
get bluetoothd running on root first by running bluetoothctl.  Then I quit
out of it.
Over on the regular user shell, I executed pulseaudio --start -D.  At that
point, I was able to run bluetoothctl as the regular user and get it to
respond.  I was able to connect to the speaker and the play button on the
speaker lit up and there was a little chirp from the speaker.  Running
pacmd list-sinks showed the speaker as a sink.

Sounds great, right?  Wrong.  Shortly after, the play button light went
out with three beeps from the speaker and more troubling, PulseAudio shut
down.

The output from systemctl -l status bluetooth is as follows:

I¹m not sure if this is where the problem is or if there¹s something in
the pulseaudio log.  Here¹s what this output looks like after the daemon
starts:
