All of the sudden I no longer have a functioning built in microphone on my iBook 500 dual USB. The preferences say no input device. Anybody else seen this happen? I am afraid that it some how lost the physical connection I assume the lead(s) pass through the hinge to get from microphone (next to LCD) to MOBO. Any suggestions??
