I ran an optical cable from SAMSUNG 65-Inch Class 4K Q60D to receiver and the sound just don't cut it. Some of the movies I play through 4K blue ray player doesn't even show that the true sound is coming through to the receiver. My receiver, Sony, shows a blue light when it is receiving and delivering digital signals. My old television UN65KU6300 65-Inch 4K Ultra Smart LED TV worked perfectly. Just ran the cable and the sound came through beautifully. The sound from my newer television is so **bleep** that I had to run the optical cable directly from the 4k player to the receiver. And what I can see, you only have two options, receiver and television. Can someone help with this problem or should I have bought a better television
