Hi @Ravica3.

Thanks for reaching out and for bringing this up to our attention. This is quite odd, but let me help and try to see what’s going on.

To better understand, if not Dolby Atmos, what audio signal are you getting on Disney+ plus instead?

Using the Sonos app, navigate to Settings > System > About my System > Sonos System Info >  Audio In to check which audio codec type the HT product is receiving.

Kindly submit a diagnostic report through the Sonos app while the specific content is playing, and reply with the confirmation number. I'd start by reviewing your system as well as the status of the devices, it will help us in identifying what's possibly causing the issue.

If you have any other questions or run into any issues,  please do not hesitate to reach out,  we are always here to help.

Hello Annazel S.

Thanks for your reply.

While watching Avengers Endgame which Disney claims has Atmos, my system is playing in Dolby Digital Plus 5.1.

The Diagnostic Code is 1808145461.

Honestly I'm not so sure this is a Sonos issues. A quick Google search will show that many many people are having this issue not just Sonos users.  Some even saying that Disney shut down Atmos.  I did not look into to much since Atmos is working with Netflix and Amazon Prime.

Hi @Ravica3.

Thanks for your response and effort in submitting the diagnostic.

I see what you mean, I did some searches as well to see if there are other users experiencing the same and this seems to be an ongoing issue.
