Loud PC speaker beep during reboot, sometimes

[Kamil Paral]

Completely randomly, my laptop sometimes emits a loud PC speaker beep while
rebooting/powering off Fedora 37. The beep is very strong, and as a PC
speaker sound, it of course ignores any configured volume level, mute
status, and even headphones plugged in. I fortunately am in a different
room than the rest of my family sleeps in, but if I were in the same room,
and were I just a regular user, this would probably be the last day of
Fedora on that laptop. The beep is that loud and uncomfortable, especially
at night.

I wonder if somebody else running F37 noticed it as well? Any hints what
might cause it and how we can fix it? It never happened on F36 on the same
laptop.

Thanks,
Kamil
