I have installed x64 and x32 flavors and I am not able to get 5.1 surround sound. I have an X-Fi Fatality card and I installed the latest drivers and can only get stereo. I then tried the on board sound with the latest drivers and the same thing happens. Only stereo...2.1 sound. I have an Intel D975XBX2 motherboard. Anyone else have sucess with multi-channel sound?
