Sony 65 xbr, hts str-ks360, bd bdp bx57, and Arris dcx3510-m. I am not getting surround sound while streaming. Which HDMI goes where? I am using and optical audio connection. I see I have HDMI arc (not utilizing that Port) on the tv, but not sure I have it on the older theater system. I would just like consistent audio, from the hts. Please give me the best connection instructions. (Oh and PS4 too.)
