Dolby Atmos walkthrough & Interoperability testing (LG CX, Bose SoundBar 900, Apple TV/ XBOX) 

@sway3566 after researching a little more LCPM 5.1.2 is same as Dolby Atmos.

@@evanthehulk I’ve read that too but how sure are you? lol because on PC I’m not able to open Dolby Atmos Settings unlike when I use my headphones 🎧 I able to access all the settings

@@sway3566 I think 5.1.2 is if not Dolby Atmos then close enough to Dolby Atmos. One of the main feature for Dolby Atmos is to have up firing speakers (for example, you can hear the sound from the top like a helicopter is really up there). And the .2 means the two up firing speakers. 🔊

I figured that out, Dobly Atmos is working with Apple TV+ native app for supported steaming films, however it's not working with local movies played with VLC media player, because of Apple intentionally removed the API needed to output any multi-channel audio in encoded form as a "bug-fix"...

That is good reference. Thank you for posting your finding here. It sure will help others out.

I have not noticed any sound delay, not in Dolby atmos or other audio format.

Try upgrading your hdmi cable. That fixed my issues.

Hi, this is how it works. So no Bluetooth involve here. 1. Connect your Bose soundbar 900 or ultra to an HDMI port that labeled eARC 2. Go to your TV setting to ensure eARC is enabled (some tv enable ARC instead of eARC by default) 3. In the TV setting, make sure the sound is set to soundbar 4. Connect your Apple TV to a different HDMI port. And because your TV is connect to TV and your TV’s sound is to Bose soundbar 900/ultra via eARC and a HDMI cable, you are able to play Dolby Atmos. Make sure to find a Dolby Atmos video and verify with your Bose app that it is indeed playing in dobly atmos.

@@evanthehulk my issue is that I have only 1 hdmi port on my tv screen
