Since this morning I am unable to record my voice on my Macbook Air 2012 internal microphone but the microphone can hear me touching the keyboard, the Macbook case…

I tried to tweak system preferences, enabling/disabling noise ambient reduction and so on without success. Tried to reboot a couple of times with no luck.

Any idea on what should I try next?

I’m on Mountain Lion (10.8.3).

could you please provide a screenshot of your mic preferences? –  cyphorious Apr 30 '13 at 11:22
@cyphorious Sure, there it is: cl.ly/image/1z0y2Z2v1Z07 –  Jérôme Mahuet Apr 30 '13 at 11:35
Hm. Interesting. One more thing you could try to to find the actual problem. Plugin some external headphones with an microphone to your Mac (e.g. the type of headphones that comes with your iPhone or other smart phones). When plugged in the prefs should change from internal to external microphone. Then try to record your voice again. If this is working you might have an hardware failure on the internal mic. –  cyphorious Apr 30 '13 at 11:46
Note: you have to plugin the headphones to the headphone jack, not the "line in" jack. –  cyphorious Apr 30 '13 at 11:50
It works well with my earphones indeed. Hardware failure really? Strange that it still records me typing on the keyboard. –  Jérôme Mahuet Apr 30 '13 at 11:50

At the moment, my best guess is that the microphone has become dislodged from its spot in the side of the case and is now just sort of floating around inside. This would explain why it picks up all the taps and noises on the case but doesn't pick up anything else well.

That's only output volume –  XAleXOwnZX Aug 10 at 18:25
Well that means it's muted. So uncheck the box and you'll be able to hear your mic –  Computer_whiz123 Aug 10 at 19:20
No... It has nothing to do with input. Thats just a mute for volume out. –  XAleXOwnZX Aug 10 at 19:33
Okay Nevermind then... –  Computer_whiz123 Aug 10 at 19:46
