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

Sure. Many of us utilize it, rather than upgrading a TV that has been recently purchased but still doesn’t have eARC. It works well, and the support on the HD Fury website and discord is quite responsive.

@HunterH HDFury are saying this is an AppleTV firmware issue. Every time the Apple TV sleeps you will lose Atmos. Can either restart the Apple TV or go into setting and toggle audio formats to something like 5.1 and then back.

Their Discord channel mentions this a lot. Some say new Apple TV firmware fixes it, others not.

I noticed this as well. I turned on beta updates on Apple TV so now running 19K545. Atmos remains after Apple TV awakes from sleep without having to amend audio settings.

Sadly 19K545 made no difference for me.

Did you change any other settings?

No. My Arcana is still running FW:0.84 rather than 0.86
