Connect all sources to TV through HDMI
Connect AUDIO OUT from TV to RCA input on Reciver using 3.5mm to RCA cable like linked by others
Connect speakers to receiver.
FYI this receiver can never give you true surround sound because you are only receiving stereo (2 speakers) worth of audio from the TV.
The receiver has Dolby Pro Logic that "guesses" the surround sound from your RCA connection and separates it out to the speaker front/rear/center speakers.
