My white macbook speakers are not working. When I check the list of audio options,the internakl speakers are not there. When I put headphones in,it's only on mono. How do I get the internal speakers back?
Diddle around the inside of the headphone jack with a wooden toothpick or something non-conductive. You need to get it to release the latch that's making it think headphones/an optical cable are plugged in.
