The issue about audio FROM the hdtv to the audio system continues to get posts like this. Tell more about the flow of the audio stream.
I have had 5.1 surround sound for a few years and have just upgraded my receiver to a Pioneer 821-k receiver. When I watch TV most programs do not play any sound thru the center speaker but some programs do. Any idea why this is and what I can do about it? It doesnt sound right when it is not utilized. Odd that my old receiver did not have this problem.
