Just purchased a Sammy 55 inch 6350 ty. My av receiver (Yamaha HTR-5950) is a dinosaur with no hdmi capabilities. Along with the receiver, my setup includes a 3.1 klipsch speakers, a blu - ray and cable box. Everything works fine when watching tv or a blu-ray disc and I can get the sound out of the klipsch speakers. Problem is whaen I use a tv app (like youtube), the only sound is thru the tv speakers. Do I need to purchase an optical cable and attach it to the digital output (back of tv) to the receiver (digital input md-cdr)? I looked all over the internet for an answer including a chat with Samasung technical support to no avail.
Thanks in advance.
