MacBook Air Mid 2011: headphone plug makes weird noises If I turn a headphone plug around in the headphone jack, it makes really loud and weird creaking noises. I just want to make sure that my Macbook Air isn't the only one which does that.

I already had a close look into the jack, but nothing seems to be wrong with it.
There is no such sound coming from mine. Sorry to say this - but it sounds like you have a repair coming your way.

It might still just be the headphones though - have you tried with different sets??
