Hi all,

My 27" ACD worked flawlessly until I installed 27-inch LED Cinema Display Software Update 1.0 earlier tonight. I have a unibody MacBook Pro that doesn't output audio from the mini displayport, when I got the ACD Friday, USB audio output worked fine. I also have a 24" ACD and audio worked fine on that as well. But after software update 1.0, I can no longer get audio output of the 27" ACD to work via USB, I even rebooted my Mac and it still doesn't work. After trying it a few times in Sound.prefPane, I now can't even select the "Display Audio - USB" option (when I click on it it reverts to the other option right away).

From /var/log/system.log, I believe this is the error related error message:

System Preferences[332]: Error ^P trying to set sOut device to 264
