Q990B dolby atmos issues with Xbox Series X

[Sptzz87]

So, this is a massive complaint post. There's, at this moment, massive issues with using this soundbar paired with an xbox series x + dolby atmos. 

My setup is Xbox Series X > LG C9 (earc) > Q990b

Passthrough, eARC on and on Xbox Dolby Atmos Home Theatre.

If you use the soundbar on any mode other than Standard there's no center channel on dashboard or any Non-Atmos game. Open up Rocket league, free play and test it. No car engine sound nor ball touches as they're 100% centered.

It works if you open a native atmos game.  It doesn't matter if Upmixing on the Dolby app is ON or OFF.

If you use Standard, the center channel works fine on dashboard and non-Atmos games, but the subwoofer doesn't work. Completely "off". It works if you open a native atmos game. 

This means that one has to keep changing the xbox's output from 7.1 uncompressed for everything apart from specific atmos games. Instead of turning on dolby atmos for everything. 

There's a massive thread with all these issues here:https://www.avsforum.com/threads/2022-samsung-q990b-11-1-4-dolby-atmos-dtsx-soundbar.3231071/page-10... 

Would Samsung be able to comment and hopefully fix it through firmware?

7.1 become 5.1, 5.1 become 3.1.

worse than before...

Hi, I have just found a solution, based on this post. You must turn on Pass-through on TV and on Xbox, don't let this devices mess with sound. And on Xbox now you can use the Atmos option fine.

Read original post. Passthrough has always been on. Xbox as well even though that's for non game apps. If the solution was "turn on Passthrough" then that meant literally no one was using Passthrough lool. Ofc that's the automatic setting everyone should use
