USB microphone not working

[Rafael Amador]

In the “Voice Over” window, had you checked your external mic as well?

You could also try switching to another input and back. Sometimes that gooses the USB mic connection to work.

nothing is working.

I don’t think you’re doing anything wrong. Have you tried restarting the app, and restarting the computer?

Yes, I even called Alesis and their last resort was reinstalling the OSX.

I have another Mac computer that is OSX 10.5 and it works just fine.

It befudles me why it isn’t working. I’ve checked every input setting I could think of. Even the Audio MIDI section.

Does the mic show up in System Profiler under USB?

Some how I got it working.

My newer mac pro, that I got in August, the mic worked just fine after restart.

My older mac I went to utilities and then system utilities and clicked “disk utilities”
and then clicked “repair disk permissions” on the hard drive the operating system is installed on. then I clicked
“verify disk permissions”
and restarted the computer and the mic works fine now.

I have another mac pro from 2005 that the mic isn’t working on. I don’t know what I’ll do on that one.

Thanks for all the help. I’m just updating this thread so future USB mic owners will try what I did to get it working.

Just thought I’d mention I had a similar problem and somehow got it sorted.

I had a Griffin iMic with a White MacBook. For some reason the iMic wasn’t appearing as an input device in System Preferences > Sound. I’d tried different USB ports, repairing permissions in Disk Utility, a full system restart and it still didn’t appear. Then I unplugged it and plugged back in, after a few moments it appeared and now everything works fine.
