Your Microphone Is Not Working?

On occasion my macOS sound system just stops working. After a great deal of tweaking, I can usually get it to behave, but it is a total pain to deal with it. I do use a third party sound App called SoundSource, but even the Mac sound system can still misbehave even when not using any third party Apps. This article describes how to troubleshoot a non-working Mac Microphone, but the steps really apply to the sound system in general as well.
