Issues With New Atmos Setup, Need Help With Diagnosing.

Hey all, just wanted to post here, as I’ve been having a few issues with my new audio setup, and trying to diagnosing wether this is an issue with the Xbox (and insider program) at the moment, or rather an issue with the Soundbar device itself. I have been part of the program for almost 9 years now, and was hoping other insiders could help me troubleshoot the issue I am having.

I recently purchased a Samsung Q930B sound bar, with two rear satellites and a sub, to be used as a home Atmos setup with my Xbox.

I am currently using an LG G2 OLED 65” with the Series X. In order to retain next gen features I have it wired through eArc (Xbox - TV - Soundbar).

Essentially, with my G2 TV settings;

Digital Sound Output - Passthrough EArc Support - On Xbox - Passthrough my Audio to receiver, and let receiver decode audio.

I was able to (mostly) eliminate the infamous Dolby Atmos audio lag/lipsync issues by following the steps detailed in this post.

So I get practically all checkmarks on my audio options, except for DTS/X (since the LG TV’s don’t support DTS Passthrough).

Issue I am having with the setup;

When I set my Xbox to Dolby Atmos Home Theater, it works fine on Atmos enabled games (such as Halo Infinite, Gears 5, etc)

But!!!

When I play non-Atmos enabled games with Dolby Atmos Home Theater audio setting, there are some issue below (compare to LPCM 7.1)

1. 
   If I set Q930B sound mode to Standard, subwoofer won't work as intended. Subwooder will be either very queit or freaking loud. Other channel works well.
   
   
2. 
   If I set Q930B sound mode to Surround/Adaptive/Game Pro(which will do upmixing to 11.1.4ch), sound only comes from Front Left and Left Surround speaker on Xbox Dashboard which sounds really weird. In-game, center channel audio is missing so I can't hear footsteps and dialogue.
   

If I switch the Digital Sound Output on the LG back from “Passthrough” to “Auto”, this seems to alleviate the issue, however this solution also brings back the infamous Atmos lipsync/audio delay, as well as blocks me out from using 7.1 & 5.1 uncompressed.

Looking on websites like Reddit and AVS Forum, it seems that many other users are also having issues with non Atmos content being up mixed through the Xbox and not properly allocating channels with any of the Samsung soundbars and setup (such as the Q990B).

But I’ve also heard from others on AVS forums, and on other subreddits when trying to troubleshoot this issue, is that no matter the setup you have, soundbars will always have issue when playing back non-native Atmos content on the Xbox, and the only way to properly get audio, is to switch to Atmos when playing back native Atmos content, and if the game doesn’t support it, to switch to 7.1 uncompressed Audio. Wether you have a Samsung Q930B or Sonos Arc, or Sony HT A7000, this issue with improper channel allocation is present.

When looking at the recent insider bugs, I do see some listed bugs around audio playback on the Xbox Series X:

https://news.xbox.com/en-us/2022/11/28/xbox-insider-release-notes-alpha-2302-221122-1730/

My question to insiders to help me troubleshoot, is are there other users with this soundbar setup having the same issue?

If you have another setup (ex Sony HT A7000, Sonos Arc etc) and using an LG OLED TV, do you also have the same issue regarding non-native Atmos playback when the console is set to output Atmos?

Is there anybody who knows a workaround to this potential issues with the same setup (Samsung soundbars like the Q930B or 990B) or a similar setup from a competing brand.

I am trying to troubleshoot down, wether this is an issue with the Xbox firmware and the insiders, and regardless of your soundbar setup, you will have issues with audio channel allocation in non-Atmos content. Or wether this an Issue with the LG passthrough, and is a problem with the Lg OLED TV’s (as I know these are plagued with audio issues in their own right), or the solution is as simple as changing my audio setup to another brand like the Sony HT A7000, and the issue is strictly with the Samsung soundbars. If that’s the case, then I can simply return this for a better sound setup.

Any help on this subject matter is greatly appreciated, as I have heard conflicted reports on wether this is an issue with the Xbox, and affects other soundbars as well, or is an issue strictly with the Samsung brand of soundbars.
