I have my 8500 receiver connected to Yamaha AV amp over HDMI which then forwards HDMI to the screen.
Whenever I turn everything on there is no sound, switching off and back on either the receiver or AV amp makes no difference. Tried in another HDMI port and a new cable and no difference.
The only thing I found to fix was to go into the audio settings and change AC3 from 'passthrough' to 'downmix' suddenly the audio comes back. Even if I exit the menu without saving the audio stays working fine until the receiver is switched off again.
