I don't know if you all could help me but this seemed like the best place to post my thread. I have a Dell 2405FPW and the Logitech 5500 5.1 speaker system. My screen has necessary input jacks to plug the RCA yellow cable (video) from my Xbox into my screen, however i am lost on how to plug in the audio cables (red and white) to my speaker system. The 5500 speaker system has 3 inputs - direct, coaxial, and optical. Is there any kind of cable that could convert the audio RCA cables to any of these 3 input jacks? THANKS in advance to anyone that can help me
