Bug report - Dolby Digital and Dolby Atmos audio drops on Sony 20/21 tv's whilst using 4k...

It seems that your TV supports Audio Return Channel (ARC). However, on the TV's specification page I don't see if it supports Dolby Atmos through ARC.

If your TV is capable to send Dolby Atmos via ARC, you'd connect your Xbox to a 4K capable HDMI port OTHER than the HDMI ARC port on your TV.

You will then get 4K resolution on the TV screen, and the TV would "forward" audio via the Audio Return Channel to the sound bar. If supported, this will then be Dolby Atmos.

It seems that the Soundbar doesn't support 4K pass through. So either you would need a new TV that supports Dolby Atmos via ARC, or a new soundbar or AV receiver that supports 4K video.

Make sure your TV and AVR are compatible with Dolby Atmos: Both your TV and AVR need to support Dolby Atmos in order for the feature to work properly. Check the manufacturer's website to verify that your TV and AVR support Dolby Atmos.

- all of my devices support Dolby Atmos

Check the audio settings on your TV and AVR: Make sure that both your TV and AVR are set to the correct audio output mode for Dolby Atmos. For example, on your TV, you may need to set the audio output to "Bitstream" or "Dolby Digital Plus." On your AVR, you may need to set the audio input to "Dolby Digital Plus" or "Dolby Atmos."

- all settings are correct

Check for updates: Make sure that your TV, AVR, and Xbox are all up to date with the latest software. You may be able to check for updates in the settings menu of each device.

- all of the devices with the last updates;

Check the audio settings on your Xbox: Go to the settings menu on your Xbox and select "Display & sound," then choose "Audio output." Make sure that "Dolby Atmos" is selected as the audio format and that "Audio passthrough" is enabled.

- all needed options are enabled;

Try a different HDMI port: If you're using an HDMI splitter or switch, try connecting your Xbox directly to your TV or AVR to see if the issue persists. If the issue is resolved when using a different HDMI port, there may be an issue with the splitter or switch.

I have a direct connection.

All other applications work properly (blue ray disc movies, games, Dolby access app, etc., deliver to receiver Dolby Atmos). Netflix and Apple TV also worked properly before.

I have the same problem with My xbox one x and 950 soundbar. I get audio delay once I enable Dolby atmos via the audio settings on my hdmi, but the soundbar works great with all other devices, cable TV, apple TV 4k. I've literally tried everything and
I'm thinking is has something to do with the Dolby atmos application. I've used optical and other sources and they sound good, obviously not Dolby atmos but they work. I don't think it's my TV or soundbar. I've also replaced the xbox one x to a new xbox one
x and same issue. It has to be a bug in the atmos connection from the speakers to the xbox. It's super frustrating. Not sure what else to do until I new update comes out.

Same, I can only get atmos with 1080p

When I switch to 4K, audio goes to dolby digital

Is there a fix yet?
