LG OLED CX & Onkyo HDMI newbie No rear channels in 5.1 Receiver information says: 5.1 in 5.1 out (1 Viewer)

Hello Folks

I have a problem getting output from my rear channels using HDMI. I've searched through the TV and receiver manuals looking for options. Everything I've tried has failed. A clue is that I am not getting anything out when the TV is the source and streaming movies. Can someone point me in the right direction? I would have pulled my hair out if I wasn't bald already.
Thanks for reading my post.

Are you getting sound from the center channel?

Are you getting sound from the center channel?

Yes, I am. There is an Info View from the receiver. Audio choice says 5.1 both in and out. The channels are still working as I get pink noise calibration through.

I can get 5.1 from the TV streaming apps if I connect the optical output to the receiver.

Are your ARC settings correct? It may not be processing the sound to 5.1, especially if an optical cable is giving you the correct formatting in the same scenario.
