Is your setup connected as: Apple TV box →[HDMI]→ TV →[HDMI eARC]→ soundbar ?

Does the TV have eARC? Is that HDMI port activated for eARC use (regular ARC may be default)? Regular ARC is not enough for Apple TV’s Dolby Atmos output.

For TVs without eARC, there is an add-on solution: HDMI eARC adapter (e.g. this one or this one).

Be sure to set the Apple TV to output audio to the TV over HDMI. Then set the TV to passthrough audio to the soundbar.

Apple TV’s Dolby Atmos output would be in Dolby MAT format (like PCM), so soundbars would need to support that, else it won’t work. Ask the manufacturer’s support staff if unsure/not documented.
