Volume locked in my MacBook
I have a MacBook Version 10.15.1, OS Catalina
The volume appears to be locked. When I press the volume keys, all i see is the speaker icon with a cross underneath. It won't let me adjust it in the toolbar. In settings > sound, there is no input or output devices found, nor will it let me adjust the output volume from there.
I tried restarting the computer, plugging in headphone, and nothing has worked.
Has anyone had to deal with this?
