The red light is a digital audio output signal - the socket can deliver both analogue and digital and is switched inside depending on what's inserted. If it's got stuck in that mode try inserting/removing a regular headphone jack while wiggling it a bit.2.4 Ghz 15" 4GB RAM 500GB/7200 Unibody MBP, 60GB iPod, iPhone 3G 16GB, Mac OS X (10.6.2), Assorted other Mac's and PC's running OSX, Linux, WinXP, Win7

Currently Being ModeratedDec 13, 2009 10:07 PM (in response to iVmichael)The original post mentions that the light stays on only in Windows - my guess is that there's a problem with the Windows driver for Apple's audio hardware - missing, or buggy. Apple's multi-purpose digital/analog audio port is pretty unusual.MacBook Pro 13", 2.26Ghz,4Gig, WD 320G 7200 HD, Mac OS X (10.6.1), Logic Studio 8, Focusrite Saffire
Currently Being ModeratedDec 14, 2009 10:33 PM (in response to lobotomy628)I think that the answer is probably that you simply need to update your version of BootCamp Windows Drivers - see http://support.apple.com/kb/DL967
Some people seem to suggest that installation of updated 'Realtek" drivers in Windows may help.
Given that the problems seems to involve interaction between Bootcamp and various drivers I doubt that reinstalling your Windows OS will resolve it, though, as I don't use Windows, I'm not in a position to test it myself.
