Hi guys,
Weird issue: I’ve my LG C9 TV set to passthrough/eARC, and Dolby Atmos works just fine. However, when I play non-Atmos content (5.1) I can hear no dialog track from the movie, and the Sonos App shows Stereo 2.0 as played content.
Turning off eARC or changing from passthrough to Auto or PCM makes 5.1 content hearable, but only at Stereo 2.0 and not 5.1
This is only affected by content from Apple TV. Native TV apps are playing correct sound formats via Arc
Any help would be most appreciated.
