Onkyo tx NR 616Sony BDP-S5100 3D Blu-ray Disc Player I have Avatar Bluray disc, when I play this looks like I am getting only 5.1 audio out (no sound from rear high surrounds). I set my receiver in 7.1 config. My Sony player has youtube app. When I play any video from that, I get sound from all speakers. Can someone please help me fix this? I like to have sound from all speakers when I play blueray discs also.
