I have several connectors. One has green, red & blue male connectors and the other has red, white and yellow male connectors. I can get video to work by using the green, red and blue connectors but unable to get any audio. Any suggestions? Do I need both of these connectors? They were previously on the dvd player when I was going through the satellite box. But I have moved them around so many times, I don't know what goes where. Help!!
