Dolby Atmos

Do you have the Apple TV box? If so, which model? Identify your Apple TV model - Apple Support

Verify that the chosen content has Dolby Atmos available in the stream. Not all content will have that.

Does content in other apps still have Dolby Atmos available? If so, then it is an app issue or content provider issue. Then contact Disney about it.

Verify that Audio Format is set to Auto (Change Format Off), and with Dolby Atmos set to On, for content that has that.

What is your audio setup?

Thanks Urquhart1244!

I'll check the ATV model number when I get home, but it is the 4k one that offers Dolby Atmos.

I feel like I've already done the settings you're suggesting, but I'll try it again. I did check my receiver settings on my Denon X1600H (7.1 speaker system) and I believe those are correct (see link for details: Having issues with ATV 4K! Dolby Atmos no… - Apple Community). If that doesn't work, I'll call Apple Support for additional assistance. Or, I may just return my ATV 4K. I bought it this last Sunday, so I can still return it.

Btw...is there a way to turn off the PCM option on an ATV 4K?

You mention troubleshooting done for the device, but you hadn’t specified anything done specifically around your speaker system. If this a receiver based system or a Soundbar? Did you do a reboot there? Check firmware? Check cables?

If there were a Disney problem I would the think it’s specifically for the chromecast as I do not see any problem with ATV or reports from other users. The fact that you’ve seen it come and go between your devices is why I suggested checking the speaker system itself.

In any case, hope you’re able to resolve. Good luck

Yeah, make sure to check ensure that it is set to auto for audio output (Settings > Video and Audio > Audio Format ) and also that quick start is enabled (Settings > Apps > iTunes Movies and TV Shows > Quick Start.)

If the issue is isolated to an app, then it would be a service issue and the provider would need to investigate in order to rectify. If it is experienced system wide then Apple support would be a good step so they can run through some further things with you to narrow down the issue.

As for the audio settings. Apple TV uses the MAT container to send out LPCM when set to auto. The only other option is to set it to change format and select DD 5.1 or stereo.

Hopefully some other Disney+ subscriber will chime in, because I canceled that a while back.

Am currently using Disney Plus on ATV 4K and Atmos continues to work on my system.

You're welcome.

Have you done any troubleshooting with the sound system?
