First time Boot Camp user. Running SL and decided to put Windows 7 (64bit) on using Boot Camp. Install seems ok but I have a red light on in my audio port. I have installed "Boot Camp Software Update 3.1 for Windows 64 bit" on the windows side. All this seems to do is update the nvidia drivers when I run it... Have I missed a step/update?? Is this a bug? Thanks for any help.
