I have a 77” LG C1 OLED TV and a Marantz AV8802A processor. I’m trying to pass Dolby Atmos from Netflix on the TV to the Marantz via HDMI ARC. I’ve set the TV to output the audio via HDMI and the Digital Sound Output setting on the TV is set to auto. The Netflix app is playing Dolby Atmos but the Marantz detects it as Dolby Digital + 7.1. I know that Netflix uses the compressed version of Atmos with Dolby Digital + encoding but the Marantz AV8802A doesnt recognise it as Atmos. Has anyone else experienced this? I wondered if it might be some kind of HDMI compatibility issue. Any suggestions would be welcome.
