Help with my Denon AVR-1609 receiver? - denon ps3 hdmi no audio

I just connected my PS3 via HDMI to my TV for video and optical audio port on my receiver (receiver IE does not support audio over HDMI). Cox, my cable box HDMI Video TV, digital audio to my receiver. I have no sound of light for the digital Dolby Pro Logic 2 (only FR I FL DC SUB), there is no sound. It also provides the optical receiver. RCA even tried to use my PS3, and led all the configuration settings appriopriat silence continued until May speaker. Do you believe that the recipients or bad that I no cables or what?
