Should I be running Dolby atmos or stereo uncompressed for my Astro A40’s ?

Stereo uncompressed will deliver you the highest quality audio

The Xbox audio settings I have available are as follows:

HDMI audio:

* Stereo Uncompressed

* Dolby Digital

* Dolby Atmos for Home Theater

Headset Format:

* Stereo Uncompressed

* Windows Sonic for Headphones

* Dolby Atmos for Headphones

* DTS Headphone:X

Tried all of them. Nothing helped.

If you're using an Xbox One or One S (not sure on the One X) the only Dolby Atmos support is the Headset out jack on the Xbox controller.

The HDMI audio out options on the Xbox are located here -

- Settings > Display and Sound > Audio Output > (options) Off - Stereo uncompressed - 5.1 uncompressed - 7.1 uncompressed - Bitstream

You'll probably have to stick with Stereo uncompressed as the audio setting on the Xbox.

Based on page 14 of the manual of that sound bar, it only supports 2 channel input and it simulates 5.1 out

Yes I follow all the steps , actually netflix recognize dolby atmos content but any sound is produced by the soundbar

I'm not sure what you mean by "Yes I follow all the steps".

Have you got audio out from the Xbox and into your sound bar now?

No Xbox recognize my dolby atmos soundbar because i can setup in the audio settings uncompress audio bitstream and also I’m able to select home theater dolby atmos and then I’m able to open netflix and for example select the tv show content punisher and
The opción to select dolby atmos audio is able but nothing happens still no audio

The Xbox One or One S will not recognize the Dolby Atmos. That feature is for the Headset option on the controller only.

You state - "netflix recognize dolby atmos".

- Are you using the Netflix app built in to your TV?

Try this, run your HDMI OUT from the Xbox into the TV. And on the Xbox choose Stereo Uncompressed. See if the audio from the Xbox is working into the TV. I'm assuming you're running Out from the TV into your sound bar. After you have that done and the basic
stereo sound is working then change the other audio settings one at a time on the Xbox to 5.1 and 7.1 and then Bitstream and see what the TV passes through to your sound bar.

Hi yes i tried that, i have audio for 5.1 and 7. 1 but when I choose dolby atmos via home theater actually with my soundbar dolby atmos compatible I received video but no audio .

Astro A40's are better. I tried the Xo sevens but it is a stereo headset for 159.99, Ridiculous. Get Astro A40's or A50's. They are super comfortable they have memory foam and they are one of the best headset manufacturers. And they are Surround sound.
