Any ideas or do I need to go to the Apple Store?

there is a Audio Midi Setup.app in your Utilities folder—see if there is something there, use spotlight if in doubt

To trouble shoot further you can:

—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support

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

—A SafeBoot How to use safe mode on your Mac - Apple Support will sort many anomalies

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, font cache, etc., third party system modifications and system accelerations are disabled.

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

a reboot will put it back to normal mode.

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

unplug all third party peripherals

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

all known to cause issues on the macOS
