Have Samsung tv that supports Dolby atmos. Made changes to the tv settings to not use PCM and send the raw audio to the home theatre system that includes arc, mini sub and 2 era 300s. Arc connected via hdmi eARC. Video on Apple TV supports Dolby atmos. Still the audio in shows empty and the status says HDMI and PCM2.0. What should I do?

What specific Samsung TV model do you have? What specific Dolby Atmos source are you testing on the Apple TV?

Try this:

Disconnect everything from the TV and unplug the Arc and TV from power for a couple of minutes. Plug everything back in but keep everything disconnected. Make sure Anynet+ is enabled in the TV settings. Run TV Setup in the Sonos app and follow the app instructions. When the app instructs you, connect the Arc to the TV’s HDMI ARC/eARC port using the Sonos-supplied HDMI cable. After the Arc has been successfully connected, connect the Apple TV to the TV.

Then set the TV to these settings:

HDMI-eARC Mode: Auto

Digital Output Audio Format: Pass-Through

Set the Apple TV Audio Format settings to this:

Change Format: OFF

Dolby Atmos: ON

Did what you said. I have a Samsung tv and not Apple. I was only watching a show on Apple tv (the subscription service like Netflix). The sound is better I think but the Sonos app still says HDMI and PCM2.0 not Dolby!
could it be something to do with the Tv?

Stream the movie Greyhound with Tom Hanks on Apple TV+ and tell me what audio format the Sonos app displays.

What other streaming apps do you use?

I do get good audio and if I go closer to the era300s, can hear them as well. But the app still reads HDMI and PCM 2.0.
I have Netflix, Disney+ and Now, other than Apple TV.

Test the film Black Panther on Disney+ and Don’t Look Up on Netflix.
