Hello everyone. I have a Logitech X-540 5.1 Speaker System that I connect to a Creative SB Audigy 2 ZS Sound Card. The system was given to me as a gift but they couldn't find the audio input cable to PC that went with it. Could someone please tell me where I can purchase this cable or what other kind of cable (s) I can buy that would work just as well? Please be as specific as possible because I have been looking for a long time and have not been able to find the right one just yet.
