What Likely Happened...
What is the issue us, is most likely a corrupt Audio Driver from an occurrence such as an installation..
A Few Things:
Perform the following, in the order provided...
A. Resetting the Core Audio:
Use the following command in Terminal
sudo killall coreaudiod
B. Restore form a Backup:
Created any Time Machine backups of your Mac prior to this occurrence? If so, restore your Mac from it.
C. Boot into Safe Mode:
Hold Down the Shift Key upon boot. Once at the login screen, release shift. See if it now operates as intended in Safe Mode, then restart, booting up normally, seeing if this is fixed. In Safe Mode, only necessary items load (i.e. the caches), and new preferences are set aside.
D. Reinstall the macOS:
As a last resort, you may need to reinstall the macOS
1. First, Back up your Mac:
Create a Time Machine backup of your Mac, so that you can have something to restore your Mac from, should anything go wrong with the transfer.
2. Then, Reinstall the macOS:
Nothing would be deleted. It's just that items(i..e. audio drivers) become corrupted or deleted, and a reinstall would fix this. They would be replaced or reinstalled back to where they should be. Go Here: How to Reinstall macOS from macOS Recovery - Apple Support
