Problem with Internal Microphone.

I'm having a bit of bother with the internal microphone on my macbook pro late 2011 model.

It is working fine with every application apart from Premiere pro 6.0.

I just cannot get it to register any input whatsoever.

Have tried doing a pram vram reset 3 times.

I have also looked in the Audio Midi setup and this is what I get, but no matter what alterations I do, none of them are working.



I also noticed that I don't have one that is called Built-In Microphone and other people seem to. Is that a problem?

The input devices shown on Premiere pro Preferences--->Audio Hardware does not have the option to select built-in microphone, only built-in input.

Any ideas of where my problem may lie? Freaking out because my project is due in soon and I still need to record the voice over on it.

Thanks for any advice.
