I just replaced my Onkio 5.1 with a Pioneer Elite SC-71 7.2 AV receiver. I replced the VGA graphice card in my PC with an Asus HDMI card Can Pioneer Elite SC-71 support output digital-connected sources to Zone 2? If yes, which ports? I can get sound out of Zone2 only when I use my iPhone. But I can't hear any sound from TV connected to SAT/CBL port or PC connected to HDMI 2 via RAC supported HDMI cables. What am I doing wrong?
