Thx a lot Man!

Holy cow! I have been trying to figure this out for 2 weeks now! My Bose app says the same thing LCPM 5.1.2 every time when I use either my Xbox X or my PC ! So I’m not going crazy . Also on PC via hdmi I’m not able to access any of the setup option in the Dolby app with this setup

Hi, I have extraly same setup with you: a LG CX TV, Bose soundbar 900 and Apple TV 4K 2022, but I can not turn on Dobly Atmos with VLC media player on apple tv, could you tell me how you connect the apple tv? I connect my Apple TV to LG CX HDMI 3, and Bose soundbar 900 to LG CX HDMI 2 (eArc), but I always get LPCM 5.1 instead of Dobly Atmos...

[@lvbeck]

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"...

[@evanthehulk]

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

[@sway3566]

I read somewhere that the Bose app isn’t coding the correct format but we may be still receiving Dolby Atmos regardless. I’m gonna use my pc tonight on my C1 and look up the info on the TV .

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

[@sway3566]

@@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

[@evanthehulk]

@@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. 🔊

[@Brocks38]

Are you experiencing notable sound delay by chance? It is well known that there are a lot of issues with Xbox in conjunction with atmos and this particular tv

[@evanthehulk]

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

[@darmelinceo]

Try upgrading your hdmi cable. That fixed my issues.

Hello, can it connect to Apple tv in bluetooth ? My Apple tv hdmi port is used to connect to the screen monitor for the video so I dont have any other hdmi port available to connect the Bose soundbar

[@evanthehulk]

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.
