My internal microphone dead after replacing hard disk

Hello,

I fix computers for a living, and with Macs, one thing that frequently needs replacing is the hard disk. No problem....get a new one, carefully replace it using the excellent iFixit guides (which I know by heart now....) and then install Mac OS X, migrate and voilà, good as new!

Almost.

I've had a number of people tell me that the microphone is no longer working. The thing is, and I've checked again and again and again, I never touched the microphone cable. It's very well hidden behind/under the iSight camera (and ambient light and camera "on" indicator) and the cable snakes around behind everything and is under tape and so on.

So, now I really worry about replacing hard disks. Such a simple procedure, but if they're gonna lose their microphone... not good.

I really have no idea what it could be..... Any ideas? Better yet, any solutions?

Please help.

I've read a few comments on different forums, such as this one, about the microphones in these computers, and I wouldn't be so sure that the issues are your fault. Microphone problems seem to be pretty common on these machines. Some can be solved by a reboot, PRAM reset, or even unplugging and reconnecting external speakers or other peripherals. Try the PRAM reset on the next one that you fix and see if that fixes it. You should be able to easily test the microphone in the audio settings menu.
