I can’t get ANY sound from my Apple TV 4K through my LG 55C7T to my new Sonos Arc. I’m fully aware that due to the lack of eARC on this TV I can’t get Atmos pass through.
I have set the ATV to output 5.1 but nothing is making it to the Arc. The only way to get sound is Airplay but this has other shortcomings.
Audio from the TV itself goes through to the Arc with no issues, including Atmos.
