Just purchased the new late 2012 27" iMac. Have tried 3 pairs of headphones, all work with my iPhone but when plugged into back of iMac, they do not show up in Sound>Output as an option. Only internal speakers and Apple TV.


I have pushed...hard. Not the issue.


Tired changing Audio Midi settings to 32-bit floating. Didn't do anything...


Any thoughts?



iMac, OS X Mountain Lion (10.8.2)
