[arch-general] sporadic strange PC speaker sounds

[J. C.]

Hey hey,
occasionally I hear a short "tune" on my pc speaker. It's too unexpected and 
too short to try lsof to see which process is using the pc speaker.

The sound is reminiscent of old console games. It's several short notes, all 
in a blues pentatonic.

this has been an issue right from the installation. The only special daemon 
running is brltty, which at least didn't use to make such sounds in the past.

Can anyone suggest a process or a method of finding it? It only happens a 
couple of times a day, but this could be a problem when recording with the 
microphone. On the other hand, I can't turn off the pc speaker, since I rely 
on BRLTTY and other signals in non recording contexts.

Thank you and

best wishes,

Jeanette
