I have a macbook air 11", and after upgrading to mountain lion, my headphones are not working.
I have tried with multiple headphones and multiple software (itunes, skype, etc.), and I can´t hear.
MacBook Air, OS X Mountain Lion (10.8.2)
First, turn the volume up.
Just kidding. 😉
Do the internal speakers work?
Check Audio MIDI Setup (Applications -> Utilities).
If all looks good but still no sound, ask yourself - and check - if any 3rd-party apps or drivers are installed and running (-> Login Items?) that deal with sound. Update to ML-compatible versions or completely remove them.
