I have two Thunderbolt Displays plugged into my laptop, and as a consequence, two additional audio devices become available. I find that even when I configure one display as the default output and input device, the actual behavior I get is usually unpredictable and rarely reflects the configuration I set.
I will never use the mic or audio on one of the displays. Can I somehow delete the device or otherwise deactivate it from OS X? Some sort of equivalent effect to what you get in Windows when you go to Device Manager, right-click the device, and selecting "Disable" (or whatever the text is, going from memory here)? Maybe a plist I can edit somewhere?

I've done this before but my mac isn't in front of me right now to double check. In the utilities folder is an application Audio MIDI Setup. There I believe you can disable audio devices.
3Disabling a device can't be done from Audio MIDI Setup :(
Someone suggested which can do it (not my discovery). In typical Mac fashion this feature isn't free.
