Hi All, I just received a Onkyo TX-NR616 and updated to the latest firmware immediately. I have it hooked up to a projector, hd cable box, ps3, Xbox 360, and apple tv all via hdmi. I get the picture through each source, but no audio through the speakers. I have all the speakers hooked up properly, 2 floor standing speakers, center channel, and subwoofer - still installing in wall surround sound speakers. The receiver is not detecting any speakers when I go through the set-up, but everything else works fine, it has to be a setting that I'm messing up. Can anyone help?! Thanks in advance!
