How do I connect a Samsung smart tv, Mts cable box, lg blu Ray to a Sony dvd surround system? I have Netflix on the smart tv but it won't play through surround just tv sound. Also can't get surround for blu Ray.. It only plays surround for cable and dvd.. I probably hooked up something wrong.. I have 3 hdmi cords and one optical audio cord.. How can I hook them all up so that I get surround for cable, smart tv and blu Ray?
