Passing HDMI audio to AVR
Attempting to use my AVR for the Roku audio. Have the soundbar, but I prefer to use my audio system. Do not like using the sound bar for listening, hard of hearing. Besides, I am picky when it comes to audio.
Have the HDMI cable connected to the HDCP 2.2 inputs, but do not get any audio signal pass through. Using the optical output to feed my disk recorder for music from my digital library. This is the way I prefer my setup to be. If I can not do it this way with the soundbar setup, then I will get rid of it and go back to an Ultra device.
There are no settings in the Roku for using an AVR. You connect the HDMI output from the Roku to an AVR HDMI input, then the AVR outputs the video to the TV and plays the audio through the AVR's speaker system. Depending on the Roku player model, your audio settings should either be on Auto, or if the Passthrough setting is available use that one.
Ah, I think I misunderstood. You don't have a stand-alone Roku player, but instead a Roku Soundbar with a Roku player built in. In that case, you have no way to get the Roku sound into an AVR. Since it's built into a soundbar, it has no audio output capability. All sound is processed by the soundbar itself. The HDMI port is only for sending the Roku's video output to the TV.
