All of a sudden, my plug-in speakers stopped working. I checked all connections, and it did not work.
There is hum and feedback while plugging the connection in and out- but no sound when fully plugged in.
I plugged in a pair of headphones into the jack, and it, too does not work.
Rebooting does not help.
The built-in speakers are working.
Is there a setting to change?
iMac 24″, macOS 12.3
I had this problem on my Apple Mac-mini 1M with Macos Monterey 12.4.
I tried starting up in safe mode. That is not easy, because when you keep the power button pressed the Mac-mini shuts down.
After a couple of times trying to boot in safe mode, it succeeded. After that my earphone jack worked again. Nobody knows why this output stopped working. I hope that it keeps working, because my audio system relies on it. I really don't like bluetooth for an audio connection.

I’m still interested why the earphone output stopped working. I have never had this experience before that operation of peripherals connected with a Macintosh stop suddenly.
To check the chain is a little frustrating. I trust Apple hard- en software. So I hope that there will be fix to this. Restarting computers is so Windows PC like.
May have gone bad. I’d have it checked at the nearest Apple Store - Apple Support.
Problem solved when I shut the Mac off and restarted.
It's an old cliché, but turning off and on again can solve many problems.
Starting up in safe mode is also useful in clearing software glitches.
