I installed this new soundcard yesterday (X-fi xtreme music), and had problems getting the sound to come out properly over my 5.1 system (logitech x-530 speakers). I finally got it to work, but today when i turned on my computer. the sound was odd. so i did a channel test. the two back left and right channels are coming out the front speakers. and the front left and right are coming out the back speakers. the Subwoofer and the center speaker still work fine. any ideas?
