Hmm, alsamixer just shows a volume bar, but pavucontrol shows
"Headphones (unplugged)" as the selected and only available port,
with "Show: All Output Devices" enabled. That denies me selection of
sound on HDMI - and seems typically Leonard.

ISTM that the fallback in previous sound failure has been rip out
pulseaudio to eliminate the problems. Perhaps I'll give that a go.
Hold on, in pavucontrol, configuration showed nothing useful, but
clicking on the one item offered in Profile did throw up a long
hidden list of alternatives, including HDMI.

The UI is Leonardian in its perverse obfuscation, but it can be made
 to work given sufficient persistrnce.
