My headphones didnt work so i tried fixing it i clicked disable on the Speaker and now i cant get it back HOW can i enable the Speaker on Windows Vista?

Maybe you accidentally deleted the program that controls the sound for your computer. Go to their website and try to download the one you previously or a newer version of it. It should be virus-free, but before you do this please make sure everything is hooked up right and nothing is loose, because that could be the problem.
