  1. Macbook Pro has no sound – red optical out light

    July 5, 2011 by The Man

    If your Macbook Pro has no sound (at all) and you cannot set the volume then check if your headphone speaker has a red light. If it does then you may need to poke a toothpick around to reset it. I kid you not.

    After a day at a clients listening to files via the headphones the sound had locked and in System Preferences > Sound > Output only had Digital Out. A quick wiggle inside with a toothpick and I heard a click and the red light went off and the sound came back on. Perfect.
