Attention MacBook/iPhone users:
I lost the use of my internal speakers in my MacBook Pro last night. A weird red light (that was the optical sensor) was emanating from the Optical Out jack, no options for the internal speakers in system preferences.
This problem (following research) is present in the MacBook series, iPhone and iPods that have the optical out jack (not the conventional stereo output).
Turns out a micro sensor in the optical jack gets stuck in the inserted position, "tricking" the laptop/phone/iPod into thinking that there is a 3.5' headphone jack still present. All you have to do is plug in and unplug a set of headphones in and out rapidly (with iTunes playing on the computer/iPhone/iPod) and watch for the red light to go out and listen for the sound to return.
Alternatively, get a matchstick, insert it into the output and move it around in a circular motion and see if you can hit the sweet spot (sexual innuendo intended). The red light should go out and sound should return to your built in speakers. I recommend caution using this method.
Pretty retarded fault, and a pretty retarded fix, but it works.
