My brother got a new tv and dvd player. I went to his house to install everything for him including some old HT equipment. I used the provided HDMI cable from the Samsung 850 and ran that to his 60" sony wega. I then ran a fiber optic cable from the Samsung to the recv.(JVC 803). I put on a dvd and a message, (sound not supported) appeared on the screen. I double checked all the connections and setting, tried again but the same message appeared. I was able to get 2 channel sound though. I decided to try not using the HDMI and just used a yellow video cable and the 5.1 worked. Any thoughts as to why I could'nt get a digital audio signal while using the HDMI cable?
