How to get speakers to work on MacBook (headphones will still work fine)?


MacBook 2.0Ghz Core2Duo has no audio output through the speakers, but it works fine with headphones. Any idea what to do to fix this?

The optical audio connection is sometimes dodgy on MacBooks. There is a microswitch that can fail, and unfortunately it gives a signal that the headphones are plugged in even when they are not. About the only thing you can do short of taking it in for repair is to plug in some headphones and wiggle and plug/unplug it in an attempt to get the microswitch to actuate. Just be gentle, and know it might not work.
