This happened suddenly. Sometimes I plug in headphones, sometimes I plug in an audio system, into the small jack socket on my MB Pro 13" (November 2009).


Just today, this has stopped working and I can't listen to anything through my headphone or through my audio system.


Would this be because the socket has become defective, or is it a software issue?


All suggestions welcome.

Try a PRAM reset:




If that fails an appointment at an Apple store genius bar is a good idea.
