Mac Sound/Mute
It will not allow me to deselect the mute button, what else can I do? Internal speakers are not listed as an option under output devices.

Hello, Coletwan1272.
It sounds like something is confusing the OS.
If rebooting your Mac doesn’t fix the problem, see if the problem still happens in Safe mode (hold the shift key down at startup). It takes longer to safe boot 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 normal.
Does the problem persist while in Safe mode?
Exit safe mode by restarting your Mac normally and re-evaluate the issue again after a normal reboot.
