I've searched around and have seen this issue posted about before, but I'm not sure if the headphone port on the 15" Retina is different from the older models. Right now my sound preferences under output only have headphones and apple TV listed. There is nothing plugged into my headphone port. I've tried toothpicks, paper clips, the stick of a cotton swab, and the actual headphone plug and it only works once and a while when I wiggle it or catch something the right way. If I plug the headphones in it actually switches to digital out mode, so I cant even get sound from the headphones. For a little while yesterday the speakers worked fine when I jammed a cotton swab stick in the right way, but it eventually turned off again. It looks like there are 2 switches or sensors in the back of the headphone port, which I assume one of them is sticking? Any suggestions for fixing this? I really dont want to have to bring it to an apple store or send it in.
