I tried showing disabled and disconnected devices, and it still did not show. There was only 'Line-in (Disconnected)' and 'Digital Audio', with no spot for my Apple Earbuds. Upon investigating, I opened up the 'Manage Audio Devices' tab, and found the microphone didn't even show up in the inputs tab. I tried using different microphones, but to no avail. Everything worked fine, except when using Skype, I found that the microphone for input is not working. I recently installed Windows 10 on my Mac Mini using Boot Camp.
