When listening to any audio source and lowering the volume from the keyboard buttons the sound doesn't go down in intensity but it moves to the left speaker only.
This behaviour is visible if the sound settings are open as the pan indicator moves when lowering.

To trouble shoot further you can:
—A SafeBoot Use safe mode on your Mac - Apple Support will sort many anomalies
Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled.
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
This test will tell you if third party interference; most* extensions etc are not loaded in safe boot mode.
—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.
unplug all third party peripherals when testing
Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus
all known to cause issues on the macOS
