Does Chromecast Support Dolby Atmos?

Chromecast is an affordable option when it comes to choosing between streaming devices. However, at the time of its release, the device had a few major limitations. Thankfully, Google has come up with an update that fixes many problems and introduces new changes that have been in discussion for a long time. So, can Chromecast stream Dolby Atmos with the new changes?

Chromecast can now stream Dolby Atmos content on Netflix and Amazon Prime. Disney+ only supports 5.1 channels, when using a Chromecast. Chromecast should allow Dolby Atmos passthrough and not Atmos decoding with all of the streaming services, but not all of them passthrough Atmos correctly.

In this article, we discuss the Chromecast support for Dolby Atmos with Google TV. Plus, you can find out which apps support the Dolby Atmos sound with Chromecast and which do not.

Can Chromecast Stream Dolby Atmos?

The newly updated version of Chromecast automatically uses Dolby Atmos when available. However, there are still a handful of apps that don’t support Atmos sound with Chromecast. These applications must utilize other sound outputs other than Atmos for processing audio.

In this new update from Google, Chromecast, along with Google TV, welcomes extensive firmware improvements.

From an enhanced 4K support about AV receivers and TVs, the update introduces Dolby Atmos passthrough. Apart from the Dolby Atmos support pending for a long time, this improvement also fixes various bugs users were experiencing with the device. For instance, the “Data is corrupt” issues.

How Do You Update Chromecast to the Latest Firmware?

The update happens automatically. If not, you can manually complete the firmware update as well. Press the home button and go to “Settings.” Choose “System Update” and look for the latest firmware.

If installed, you will get a message saying that the device is up to date. Otherwise, select the available update link to download and install the latest firmware.

Make sure you reset the device completely to enjoy the improvements this update brings its users.  

What Services on Chromecast Support Dolby Atmos?

From our testing, both Netflix and Amazon Prime Video streamed with Dolby Atmos audio, but Disney+ did not use Dolby Atmos when it should have. Disney+ used Dolby Digital audio which is capped at 5.1 channels of audio.

Luckily, you can still stream almost every online content service with a Chromecast, except a few. That said, there are some apps, specifically Disney+ does not support this sound format.

Why Dolby Atmos With Chromecast Isn’t Supported for Some Apps

It’s interesting to see some apps properly using Dolby Atmos audio and other not when using a Chromecast.

This is something that should be fixed in the near future by either the streaming app or Google (Chromecast). The update is great, but there are always bugs to fix and smoothen out.

Most streaming apps, such as Netflix, Amazon Prime Video, and Disney+, use either the TV, soundbar, or A/V receiver to handle the Atmos decoding. The Chromecast only passthroughs the Dolby Atmos audio to the audio device.

Does Chromecast Support Dolby Atmos Through Plex?

If you use Plex through Chromecast, you will be able to use Dolby Atmos for streaming. Thanks to the new update that enables users to watch movies and shows with surround sound effects on Plex.

Just remember, it is crucial to set up the soundbar or home theater system where every device can process Atmos sound. And of course, the content must be Atmos-enabled as well.

So, to enjoy surround sound with the Chromecast’s latest firmware, you must connect the devices with Atmos support. In addition, the video on Plex must have Dolby Atmos audio.

Does Chromecast With Google TV Support Dolby Atmos?

The Chromecast with Google TV does support Dolby Atmos. This is all thanks to the company’s latest 4K upgrade, where the firmware brings Dolby Atmos sound together with Google TV and Chromecast. Now users can watch 4K videos with surround sound capabilities using their TVs and AVRs.

However, that’s not all. The update also introduces many other bugs present in the devices for quite some time. In addition, the changes include better security, stability, and performance enhancements.

The changelog gives Android users much-needed relief from dealing with the “Android recovery screen” issue.

If you find no difference to your current streaming experience, make sure that the device is properly updated to the latest firmware release. If the update does not happen automatically, do it manually (explained above).
