Setting up a PS3 to a HDTV with Denon AVR-1507 Receiver? - denon ps3 hdmi no audio

I would be glad to try some help to configure the TV and receiver. I have to go multi-cable AV output on TV. I have the optical audio cable going to the receiver. But no sound from the speakers.

If there is an HDMI cable to the receiver, set the PS3 to the receiver?
Or you can configure an analog cable from the TV reception? Suggestions on how to do this?
Or, what is wrong with a Cable Fiber Optic Audio?

Thank you!
