Right, I had another go with another sound device, and that reminded me of
all the things still needed to be done.

1. ensuring pulseaudio-bluetooth is installed (may need restart?)
2. (maybe bluetooth.service also needs a restart?)

3. bluetoothctl needs to be run as normal user, not root

Obviously, the device in question needs an audio sink (A2DP) to work in the
first place...,

Hopefully things work. If not, `journalctl -u bluetooth.service` might help
if only to reveal permission errors.

On error, sad things like

bluetoothd[13692]: Sap driver initialization failed.
bluetoothd[13692]: sap-server: Operation not permitted (1)
bluetoothd[13692]: a2dp-sink profile connect failed for
D0:E7:82:64:21:90: Protocol not available
(=> pulseaudio-bluetooth not installed)

could show. Or, when successful:
: Endpoint registered: sender=:1.397 path=/MediaEndpoint/A2DPSource
: Endpoint registered: sender=:1.397 path=/MediaEndpoint/A2DPSink
: /org/bluez/hci0/dev_D0_E7_82_64_21_90/fd0: fd(22) ready
: /org/bluez/hci0/dev_D0_E7_82_64_21_90/fd1: fd(22) ready

Sorry for the late reply. Since this email, bluetooth audio has been working
far more consistently. It would seem that I just need to wait for a bit after
pairing and the audio will Just Work (TM), presumably because stuff is being
loaded in the background out of sight.

Also, I got new Bluetooth headphones that seem to work far better than either
of my previous devices.

Yay for progress!
