Just bought a new Sonos Arc and new Apple TV 4K. I have the Arc connected to the TV via HDMI(ARC).

I cant seem to enable Dolby Atmos. Do I need a TV with EARC?

if so is there another workaround ?

Thanks

@HunterH Have you tried unplugging the Arcana and Arc from power for a couple of minutes?

Wonder if that has something todo with it. I’m on 0.86. 

Will ask on the Discord channel as well.

I did reset Arcana several times, and I even re-updated with 0.84, still, I only got 7.1 instead of Atmos.
