I have a Pioneer VSX 816, Samsung MU9000 ultra HD TV and standard Cablevision cable box. I have no HDMI connections on receiver so went DVD to TV via HDMI, cable box to TV via HDMI, and both cable box/DVD to receiver via digital optical. All good except I can’t use receiver/Surround sound when doing Netflix on smart TV or streaming any service. Should I remove the two optical cables and just do one from TV to receiver?
