I realized my rear left speaker was defected and I returned it and got a new one.
I currently have my Logitech speakers hooked up to my television through the light green Audio In/Out wire. And sound is working in all 5 speakers as well as my subwoofer. You said I would not be able to have surround sound just using that one light green wire. But that appears not to be the case. So I guess the orange and black wire is not needed for it to work with my television.
