Is anyone else having trouble getting their microphone to work on a Powerbook G3 Bronze Keyboard runnning OS X? With an unfortunate lack of recording support in the sound control panel, I have no way to test my microphone except with Speakable Items, and that does not work. I downloaded a third party recording program, but when it looked for input possibilities on my computer it came back with a lot of stuff that didn't make sense. Does OS X currently support built-in mics?
