5.1 not working when audio set to auto, atmos. Have to change audio to 5.1 to work correctly.
I know there are lots of topics on this but wanted to refresh to see if anyone has a fix yet. I have Sonos arc connected to eARC port of my LG. The audio formatting on my appleTV 4K is “auto, Dolby atmos”. If audio is in Dolby atmos everything is great. If the audio is 5.1 it is output as stereo PCM. I have to manually change the audio settings of appleTV to 5.1 for the audio to output correctly. Any fixes for this yet? Is it an appleTV issue, Sonos issue, or both?
