Upgraded to 12.4 recently and since plugging my M1 MBP into my external display (Samsung 34" Ultrawide), the built-in display sound no longer works. Wondering if anyone else with external displays are having similar issues post-upgrade? It's very frustrasting.
MBP is connected directly to my display via USB-C. No adapters or docking stations or anything in between.
Hi all - just an update. I did a (normal) reboot and the sound started working again. I thought I had already tried this but I gave it another go and voila. Much like my old days on Windows computers, sometimes the reboot cures all!

1 - Suggest restarting in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.
2 - Does the issue present in this mode ?
3 - Sometimes a Safe Boot followed by a Normal Boot will just put things right.
4 - If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.
5 - If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.
6 - If after performing each of the above steps is the order that have been presents and still have issues - please advise for possible further assistance.
Does the monitor offer physical or onscreen sound controls? Any change there?
Does it not appear in System Preferences->Sound?
Or is it there and selected, but no sound comes out of the display speakers?
FWIW, all the existing sound outputs, including speakers on my display (a Samsung but an older 1080p display) are working exactly as before the update.
Does the Display involved have a HDMI female connector ? If for not other reason but to Test if that connection will function better - sound wise
Using Asus 27" with Mac Mini M1, Monterey 12.4 and HDMI connection. Should is passing all Sound and Brightness controls from Mac Mini m1 to Display Asus Controls
@Luis - the issues is the latter: the monitor speakers are listed in Sys Preferences but no sound comes out.
@P. Phillips - I'll try the safe mode/safe boot stuff. Thanks for the suggestions.
Monterey 12.4 - No sound on external monitor :-(
