hi all, i came across the headphone switching malfunction under bootcamp in win7 64bit. I have searched threads saying that the new fix from apple should have fixed this. This is the one is used: http://support.apple.com/kb/DL1044 I have checked the newest version of the drivers should be 6.6001.1.25 which fix the issue. But what I get from apple is 6.6001.1.23 which didn't fix anything. Anywhere could I get the newest one? thanks!
