After leaving it, and googling, I realised I had been doing that as
the root user, but pulse (if running) gets started for the user who
is logged in.

Yes, it was.
I got that information from running
pulseaudio -v --log-target=stderr
which errored because the daemon was already running.
Killing it (pulseaudio --kill) then started it, and
pactl list short sinks
showed me that sink 0 was alsa, and suspended. But that seemed to
tell pulse it was idle (or maybe a timer elapsed), and pulse shut
down before I could run
pacmd-set-default-sink 0
which reported -
No PulseAudio daemon running, or not running as session daemon
After that, running firefox (built for pulse) fails to start pulse,
so the error remained.
But killing firefox, starting pulseaudio and then immediately
restoring firefox DID have sound. Because I suspected a timeout
might be involved, after the video had finished I closed that tab,
then waited for maybe 20 minutes, then opened a video in a new tab
and again got sound.
When that had finished, I again closed it, but this time suspended
the machine. Came back later, sound appears to be running.
My tentative conclusion is that firefox57 will start pulseaudio, but
that 58 does not. I've separately had a report that xfce starts
pulseaudio, so perhaps the solution for me is to add this to
.xinitrc.
Thanks again.
