Disabled built-in mic
Hi. I have a mac mini MC815BZ/A which has a built-in mic, but when I enter on garage band the program says that there are none "integrated MIDI in". Also, all the system doesn`t detect the presence of a integrated mic. But it's not all the problem: when I connect an external mic the system doesn't detect it. Is it possible that the hardware related to sound is broken? Or... Is it possible that the driver isn't working?
