I apologize if resurrecting old threads is frowned upon, I tried looking for the forum rules but couldn't find them. I'm probably blind.
At any rate, I'm having this exact same issue, and unlike Andrew there, I have no "Auto" setting. I can't get analog (rca stereo) or digital (optical, haven't tried coax) audio through the receiver when the input is set to hdmi, even if I set the audio input to OPT-1, OPT-2, or "Assign Off".
If I switch to any other video input type, I can get audio through both rca stereo, and optical.
anyone have a hint? Or know what's going on?
