Late model 2019 MB Pro - Just upgraded to Monterey from Big Sur and having issues with sound

I'm on a late model 2019 MB Pro. I just upgraded to Monterey from Big Sur and there is now a clicking in and out sound in the background when I watch videos. It reminds me of an issue I similarly encountered a few years back when that god-awful Catalina was first released. Any suggestions?

Uninstall all third party apps that are Cleaners/Optimizers/Anti-Virus



To trouble shoot further you can:


—Try a SafeBoot https://support.apple.com/en-us/HT201262



Takes noticeable longer to get to the login screen, does a 5 minute 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.


In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.


This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.



—Test issue in another user (or guest user) account https://support.apple.com/guide/mac-help/set-up-other-users-on-your-mac-mtusr001/mac

This will tell you if it a universal issue or isolated to your user/admin account.
