I have a Mac Mini Mid 2011 Model. Earlier when I used OX X 10.7.5 my microphone was working fine. I updated my system to Yosemite 10.10.2 and my microphone stopped working. In System Preferences-->Sound-->Input, I am getting Line In (Name) Audio Line-In port(TYPE).

I am using Iball headphones.

Try deleting the following files...

From your Home folder -


It may be worth installing the current build of Onyx and clearing out the System and User caches before restarting your Mac. Hopefully your audio devices will be set back to their defaults and your mic will work again.
