External mic doesn´t work anymore

MacBook Pro 3,1 has the same problem. None of my external mic's will work. This is crazy! The fact that this problem has not been patched by Apple yet. I should not have to purchase new equipment (i.e. usb mic) to resolve this issue. Apple.....if your listening, PLEASE PLEASE PLEASE fix this issue ASAP.

You have tried plugging and unplugging the mic several times?

Since the MBP's come with combo optical/electrical input/output jacks that have a mechanical switch to select the mode, there have been numerous reports of it getting stuck somehow and disabling the connection, although this is more common in the output (headphone) jacks. In that case, it is obvious since you'll see the red laser light shining deep in the jack, which won't happen in the input (mic) jack where the light would come from the external device.

I feel for you.

Exactly the same thing has happened to my MacBook Pro, and it is SOOO annoying.

My external mic has been working perfectly for over 4 months (that's how long I've owned the machine), and by co-incidence after the latest update from Apple (that I ran over the weekend, I've not updated for a while before this), the external microphone when plugged into the audio-in socket has stopped working.

I can't believe that it is co-incidence that so many Mac users are having exactly the same hardware fault at exactly the same time (I've seen a few stories like this around the internet), so by conclusion I'm thinking it's the update potentially causing the fault.

I've re-installed OS-X, and reset everything to ensure it's not a configuration issue. The only thing I can't do is roll back the firmware to the previous version, unless anyone knows how to do that?

John!

I just questioned why it appears (according to some) that Apple isn't supporting most, if not all headset/mics designed to work with personal computers in the world today? Especially when their advertising campaign for Mac's focuses on "plug it in and it works"? I think that's a polite and valid question that doesn't require censoring.

Exactly same problem for me than John Simmonds. Except I am on 10.4.11.
After 18 months ⚠ of external mic working, suddenly It doesn't work. I can't believe the mic needs to be external powered. My previous working mic, was a crappy 4$ microphone and it worked perfectly. I think is because of the latest update (8S2167).
Please, a solution, a suggestion, a patch...?
