As my RPC (RO 4.39) boots, I get what I can only describe as a space
invaders noise - missile being fired and missing target - out of the RPC
speakers. At very low level. But the audio is fed to an external sound
system via the rear jack - and it's not on that. This has only appeared in
the last couple of weeks. Any clues?

To e-mail, change noise into sound.

What have you changed in that period?

"As it boots" covers a long period. Can you narrow it down? I can't
remember precisely but doesn't shift-boot or ctrl-boot do the initial
power-on and POST stuff without booting the desktop - what happens then?

If sound is being played presumably one of your sound-playing apps may be
supervising it. Consider remnoving them from your boot sequence to see
which makes a difference.

Or, sprinkle some intentional sound-playing commands around and see which of
the sounds play before/after the unexpected one.

Or, install !reporter and log the whole boot process in detail then look
through the logs for errors or clues.
