HELP!! I have a Xi-Fi xtreme Gamer sound card, when I use my head phones, I don't hear anything in front or behind me, only to my side. When not using Headphones everything is OK, is there something I am doing wrong? I am plugging the headphones into my speakers.
You will probably need to plug them into the back of your sound card, there should be 3 phono plugs coming off the headphones - for rear/fronts/mid channels.
sounds like you have switched your side with your front. Or your speaker set outputs the side speakers when headphones are connected..
