Hi, this is my 1st post so please be kind.

I have a 2 month old LG OLD65BX and this supports Atmos - I have recently spent a fair bit on a Sonos setup that includes the Arc & 2 x 1sl’s. (Received the Arc yesterday)  I am trying to get Atmos through the Apple TV app from the TV and others but all I am getting is Stereo PCM 2.0 - can anyone please assist with what i can try to get this resolved

It’s also worth noting that the TV has eARC and the Arc is connected directly into this port

In the TVs sound settings menu, you need to change the sound output from PCM to Bitstream

Will I have to turn off Atmos in the settings and also change the input fro eARC?

Don’t turn off Atmos. Just make sure you enable HDMI Arc and turn eARC on.

Also be sure you have the latest version of the Apple TV app installed on your TV.

Also update the LG software by manually checking for a software update.
