    My built-in speakers just stopped working and when I go to the sound preference pane, NOTHING shows up under the output tab. Am I suddenly missing a driver or does anyone know what might be going on???

    I get no sound, not even the boot sound when I start the computer. Ack

    It's an older Powerbook G4 running Leopard.

    Plug some headphones in. Do they work?

    Further to what BV has suggested, did you have headphones in before this problem started? Take a peek into the audio out port to see if a red light is showing. If it is, then you need to wiggle and twist the audio jack of a set of headphones in the audio out port to free up the speaker cutout switch.
