My sound card or whatever says i have the Realtek HD Audio, and i just bought the logitech x-530 surround sound speakers, get home, plugged that *** up and now i only get stereo sound, from the two inner speakers, non from my back speakers or middle one. So i clicked around and went to my configuration, im using windows vista, and then changed it to 5.1, still doesn't work. Please help 🙁
