No Audio in Lion

No Audio in Lion

I recently upgraded to Lion on my Imac. Everything worked fine, including the audio. Then I installed ProTools (version 7.3.1). After the Protools installation, the audio quit working. Itunes does not play. Garage Band won't even load. (I get a message saying the GarageBand driver 10202 is missing.) When I click "Sounds" under System Preferences, I get the swirly wheel and nothing happens.

If this were a PC, I'd simpy google the necessary audio driver, download it, and move on. But I can't find such a driver when I google it for a mac.

Can someone please help? I am not a computer Geek and don't know what to do !!

iMac, Mac OS X (10.7.2), No Audio in Lion

Have a look in "Audio-Midi-Setup.app" in your Utilities folder within the Applications folder, if the audio devices are listet there.

Tried that, but when I click on the Audio-Midi icon, nothing happens. The icon heading turns from blue to gray, but that's it. No program opens up. No folder...no nothing. It's like the entire audio system has been zapped.

Never mind. Solved the problem. Found out that Pro Tools 7.3.1 is not compatible with Lion. Performed a clean uninstall of Pro Tools and everything works fine now.
