Today I received my asus xonar dx sound card. I installed it downloaded the drivers disabled onboard sound and it hasnt worked. I have a logitech z623 which Ive gotten to work but my surround sound system has seen no such luck.Currecntly I am using the sony bdv is1000. When i test it out in the asus xonar program im only getting play back from two channels thr front left and right speakers. I do have the default set to speakers and I have set the proper audio channels (im only using 2 atm). I have also disable the onboard sound.
