"OSMAC MONTEREY 2015 MacBook Pro LOST SOUND" I need help with directions on how to turn the sound back on. I was wiping/cleaning the keyboard while watching a Prime Video, and then the sound turned off. I looked online and none of the suggestions worked! What are the STEPS TO TURN SOUND BACK ON that you would recommend?! THANKS"

Troubleshoot a Muted Audio:
Type the following command in Terminal:
sudo killall coreaudiod
If an app has its own audio input and output settings, then perform things on the app itself.
Verify what your output item is.
If there are any microphones nearby, then they may be getting in the way via bluetooth.
See if an app is permitted to use your microphone.
Sometimes when changes are made to the system(i.e. updates), system configurations (i.e. for Sound) become manipulated, technically. So, reset the SMC and NVRAM. (Applies to Anted-Based Macs Only)
When you boot into Safe Mode, items load by default, with certain settings and caches set aside. So, hold down the shift key upon boot. See what happens then.
- Create a New Administrator:
See if creating and logging in as a new administrator does the trick. There may be something misconfigured in your current user - something that is getting in the way. Go to: System Preferences > Users & Groups > Unlock > Click: "+" > Create the new administrator
