I bought the platinum so I could use optical that is located on the front pannel of my pc and not the card itself. Then to use it with my onkyo reciever. The problem is when I test it with the calibration wizird it only detects right and left speakers. I have a 6.1 set up it tells me to check speakers. I did the onkyo remote test and all speakers are working great. What setting did I miss.also I put in pain killer and that gave me surround with my audigy 1 but only two speakers on 2. The audigy diognosic had no errors
