I have the DQ45EK board and I would like to use 4 speakers. According to the tech spec document for the board, retasking for the audio jacks is possible but I can't figure out for the life of me how to do it. I tried setting my speaker configuration to quadraphonic and all the other choices but I just get no audio out of my 'rear' speakers. I'm running XP and have the latest drivers installed. SoundMAX seems like a pretty convoluted program.
