It shouldn’t matter if there is audio over HDMI or not, your audio selection on your Onkyo receiver is what matters. You can confirm if there is an audio stream over HDMI by checking “Source Information” on your receiver. Have you tried connecting the HDMI cable to the GAME input (I think this is HDMI3) on your receiver and have the optical cable plugged in to OPTICAL1 of the receiver? From memory this is the default configuration for Onkyo’s. I’d then go to Source Information to make sure everything is correct…
