Dolby atmos not working right with games with SJ9 lg soundbar

I have the same problem, but my Xbox One X pushes Dolby Atmos to non Dolby Atmos movies. Also my Xbox pushes out HDR to non HDR movies. It's very frustrating that the sound cuts in n out even when I play Shadow of The Tomb Raider that's Dolby Atmos. Even
Avengers Infinity War sound cuts in n out. Since I have a Geek Squad warranty, I took my LG SJ9 to Best Buy. They tested all Dolby Atmos scenarios and never once did they have a problem with the soundbar in Dolby Atmos mode cutting in n out. There's something
wrong with the Dolby Atmos signal the Xbox One X uses that the SJ9 has problems decoding.

I have done that also fully factory rested my console and still the same thing happening

try to power cycle your console. Please hold down the power button on the front of the console for approximately 15 seconds until the power light shuts off. Wait about 60 seconds, then power it back on. Be sure you see the green "XBOX ONE" animation loading
screen when you power it back up. Then go to audio setting and set again you're Dolby Atmos Sound option

I have also got the same issue where my Xbox one s does not recognise my LG sj9 atmosphere soundbar for outputting atmos to, I downloaded the Dolby app and I keep getting error 0x80bd0038 when I try to turn atmos on in sound options on Xbox. The annoying
thing is I only brought the xbox to stream Netflix atmos programs on.

I don't think thats gonna work because it's about Dolby Atmos on a headset and not on a soundbar, my soundbar is an LG by the way, model number SL8YG, works perfectly in every way except when playing Xbox when it's passing through the TV, Dolby Atmos will
only work on the Xbox when passing directly through the soundbar
