I have an older Sony Receiver/Amplifier - Model STR-DE185 that I would like to hook-up to a new Samsung 4K TV. I have speakers hooked up to the Sony and would like to integrate the Receiver into the new Samsung TV system so I can use the speakers with the TV for movies and music. I'm thinking an HDMI out from the TV to an HDMI to RCA converter box. Am I on the right track? Thanks again for any help you can offer.
