Page 19. Match the input name you're using for the PS's video with the optical audio label.

The dish network reciever should have audio and video out on the back, If its a HD device it should also have COAX out (hd audio) get the cables for audio and feed the into a input on the back of your home theater system, there should be several inputs, usually labled like video 1 video 2, tape deck etc etc. the audio in are red and white or red and black usually, the coax connector is orange, and you only need one cable to hook that up. If you have HD audio on the dish network that will sound best in your home theatere system

Try whatever applies best below, in order...

Cable Box optical Digital Audio to Digital Audio In. (This brings TV-related multi-channel and normal audio into the receiver so you can hear it over the speakers. Turn TV volume OFF.

The cable box probably has a pair of stereo Audio Out RCA jacks. Run those directly to the TV so you can watch and hear cable programming over the TV's speakers without having to turn the system on. Turn TV volume UP.

Depending on your TV's Video In capabilities, use the Cable Box HDMI, Component (Red, Blue and Green), or Composite Video (single Yellow associated with the Audio Out) directly attached to the TV.

Make sure that your patch cables are cumming from the audio line OUT of the TV to the audio line IN on the surround amp. A common mistake on hook up is usually the problem.
