When I wanted to use the microphone in my iBook G4, Mac OS X Tiger (10.4.3), today to tune my acoustic guitar with GarageBand, it didn't seem to pick up any sound at all. I first wondered if it was a problem with GarageBand, but when I try the microphone in Sound preferences, it doesn't pick up any signal either. I tried restarting my computer to see if it would go away, but that didn't work either. It's really weird, cuz yesterday the microphone still worked and I was very easily able to tune my acoustic guitar in Garageband. The only thing I did on my iBook between then and now is play THPS4 with headphones on, so I don't think I blew up the mic or anything like that. I really don't get it. My System Profiler says:
Internal Microphone:
Controls: Left, Right
Playthrough: No
PluginID: TAS
Is that all OK? I have no idea what it means or if it's even related to my problem, but thought I would just mention it, just in case.
Input volume in Sound preferences is set at 50%. Setting it lower or higher doesn't make any difference: the Input level shows zero input at all times. "Choose a device for sound input" is set to Internal Microphone/Built-in (Name/Port).
If anyone can help me out here, I would be ever so grateful! I really need to be able to use the microphone in order to record music and do voice chat. So, if anyone of you knows how I can fix this, I would really love to hear about it. Thanks in advance for your help.
