I need some advice on how to connect my current older surround sound system with a newer smarttv so that I can have audio from the apps thru my system. I’ve done a lot of reading but there’s an overwhelming amount of information not all of it consistent. Onkyo TX-SR600 reciever Samsung 6 Series Smart tv Generic set top cable box 1st question: should the output from cable box go directly to tv or receiver? I’m using a HDMI cable to the tv at the moment. Then an optical cable to the receiver for audio. (The cable guy set this up). The receiver doesn’t have HDMI connection ports or even ARC just optical, Component, Analog, S Video and Coaxial. I also have a Mitsubishi DVD player attached already to the receiver using component connectors. Thanks for any help.
