Before you say anything, I'm on a laptop, and I don't know what to do to get it back, I've tried everything, well. Everything I can understand, and most of them are basically saying,"Plug it in the back." Or "Use the back output." But I don't have one so I really need help. My headphones work fine and so do the speakers. My headphones used to play sound but now they don't. Got any uh, clues or any way to help??
