I have an interesting problem that has developed: Sometimes the headphone jack on my Mac Pro doesn't detect headphones being plugged in and does not play through the headphones, it continues to play through the Internal Speaker. In the sound preferences, it calls it "Internal Speaker". After a reboot, the headphone jack works fine, but after two or three unplugs, it fails to work until the next reboot.

The weird part is that it's detecting the headphones getting unplugged and stops playing music on iTunes, but it doesn't detect when it's being plugged in to swap the audio.

Mac Pro (2009, 4-Core), Mac OS X (10.6.4)
