well as i'm a dj i work with pro soundcards and stuff, i guess i would got out if i got some time on your computer. Anyway  audio works with a driver, windows, asio, kernel, whatever, you just decide which one you like te most. Make sure you got one of these, in circumstances these can be removed accidently... Also, you have much more faders than just those of your windows mixer that opens with a click on the litte speaker. Rightclick and select properties may open a new window, and you'll get to new faders defenately. Some programs mute sound automaticly, if you don't shut off right or the program crashes you'll stick with it... big chance it was just a setting..

But hey you got out, system restored are handy! but you can keep it in mind.
