My startup chime has stopped working. It has worked in the past, but not anymore. How do I restore it?
Mac mini, macOS 13.0

Verify your sound is not muted when you shut down and restart your mac—and try again.

If you can't hear sound from your Mac speakers - Apple Support
you might be able to reactivate and/or deactivate the chime with terminal commands.
to enable it, open terminal (found in applications > utilities) and paste in this command
sudo nvram StartupMute=%00
and enter your admin password when asked.
then restart your mac to test. if that didn't work, you can try disabling it before re-enabling it. to disable it, paste in this command in terminal.
sudo nvram StartupMute=%01
again enter your admin password when asked.
Did that, didn’t help. Also, toggling it on in Sounds prefs didn’t work either. It worked in Monterey, but not in Ventura.
I and others have had this issue come and go for the last several OS updates. My sound returned after the next update. Never determined why.
