I've purchased a new pair of headphones today for my computer. My computer is brand new so it has a built in television too. For some reason when you're listening to the television with the headphones on the sound only comes out of one side (the right side), but when you for example watch a YouTube video on the computer they work perfectly fine. It's not the actual headphones because I've tried it with 3 different pairs. Does anyone know what's wrong?
