Today I verified the HDMI input worked correctly by sending a signal from another HDMI source. The AVR immediately detected the signal. I have verified that "HDMI" is the selected input both in the setup and in the digital display of the input. I am familiar with the selection of the input since I regularly switch back and forth between Optical SPDIF and HDMI. The optical input still works perfectly. Analog audio also working fine.
If you happen to find the solution, that would be great. Otherwise, I can use the Optical output. I would guess the sound quality will be as good or maybe even better than HDMI via SPDIF/Optical.
