Ive tried reinstalling and all that shiz.
I plug my headphones into either the front or back and they are detected as headphones or speakers (depending on if i put them in front or back)
But no sound comes out of them! And they arent on mute.
BTW: Im using Win 8 Consumer Preview, it has been working fine until yesterday when i installed a belkin wireless card, which i have taken out and it still doesnt work.
