My computer speakers stopped working after I updated to Monterey. My sound is up and I have selected my mac computer speakers as the output.

Did you try rebooting more than once since the upgrade?

To trouble shoot further you can:

Takes a bit longer to get to the login screen, does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

Make sure nothing is plugged into the Mac's headphone jack.
