Hello, twistedtuneman.
Sorry that you're having this trouble with your Mac speakers.
Doe the same thing happen when you login to another user account? If you don't have another account to test this with, add one by going to System Preferences > Users & Groups.
Try resetting the NVRAM. The NVRAM is a special memory section on your Mac that stores data that persists even when the Mac is shut off, such as volume settings and screen resolution - it's the information the computer uses to maintain settings after a reboot. You may have to do each of these several times because sometimes that's what it takes to stick.

If neither of these actions resolves the problem, see if the problem still happens in Safe mode (hold the shift key down at startup). It can take much longer to safe boot (10 min) so be patient.
How to use safe mode on your Mac - Apple Support
Safe mode forces the OS to clear certain caches and logs and do other miscellaneous housekeeping. It's non-destructive to user data so is safe to do. Very often certain weird software behavior is corrected by simply logging in this way as a troubleshooting method. When you're in safe boot, the machine will not be at its best performance, especially with graphics, but that's expected.
Does the problem persist while in Safe mode?
Exit safe mode by restarting your Mac normally and re-evaluate the issue again.
