I have new LG TV with eARC port connected via HDMI to a Beam 2 and 2 Era 300’s and a Sub Gen 3 for my surround system.  Apple TV 4K connected to the TV via HDMI.  According to the S2 app, I’m getting a Stereo PCM signal even when streaming a movie offered in Dolby Atmos. 

I can play Dolby Atmos music to the system (sounds awesome!!)

Any suggestions?

Set the TV to these settings:

HDMI Input Audio Format: Bitstream

Digital Sound Output: Pass Through

eARC Support: On
 

Set the Apple TV to these settings:

Change Format: OFF

Dolby Atmos: ON

It worked!! Thank you. The missing setting was HDMI Input Audio Format: Bitstream.  Appreciate your help! Cheers

One more question:  When a Dolby Atmos source is not streaming, I get Multichannel PCM 7.1.  Is that to be expected?
