Yesterday’s premiere of Amazon’s latest original series, Tom Clancy’s Jack Ryan, marked the arrival of the first Prime Video content to support Dolby Atmos surround sound. Some Fire TV owners eager to finally fully utilize their advanced home theater audio equipment have been perplexed to find that the new TV series isn’t lighting up the Dolby Atmos indicator on their A/V receiver. That’s because Dolby Atmos is not automatically enabled, like other surround sound formats, and must be manually selected.
To watch Tom Clancy’s Jack Ryan with Dolby Atmos surround sound, you’ll obviously first need a Dolby Atmos compatible streaming device. The Amazon Fire TV 3 (pendant) and Fire TV Cube are the only two Fire TV models that support Dolby Atmos. Some smart TVs will also be able to stream the series with Dolby Atmos through the Amazon Prime Video app built into the TV’s operating system. The Roku Ultra and Apple TV running the latest beta version of iOS 12 should also be able to stream with Dolby Atmos.
With compatible streaming equipment, you’ll then need to ensure that you’re watching the correct listing for the series. Unfortunately, Amazon complicates things by having separate listings for Ultra HD versions of their content and 1080p versions of their content. Only the Ultra HD version includes Dolby Atmos audio, so look for “[Ultra HD]” in the title of the content. Simply searching for content often brings up the 1080p version and adding “Ultra HD” to your query usually brings up no results.
The best way to find the Ultra HD version is to find the row of content labeled “Prime Original Series in 4K Ultra HD.” This row can usually be found in the new Prime Video section on Fire TV devices. It is also sometimes featured on the Fire TV home screen and the “Your Videos” section. If you’re having trouble finding it, you can go to the Amazon.com listing for the Ultra HD version and add it to your watchlist through the website. It’ll then appear at the top of the “Your Videos” section of the Fire TV interface.
Once you’re streaming the Ultra HD version through a Dolby Atmos compatible device, you then need to manually select the Dolby Atmos audio stream. While the series is playing, press the Menu (hamburger) button on the remote and select “Audio” from the menu that appears in the lower right corner of the screen. Press right to get to the “Audio output” options and then select Dolby Atmos.
Dolby Atmos surround sound audio will likely not immediately start once it’s enabled. That’s because the non-Atmos audio is likely still stored in the stream buffer. After a minute, the stream should automatically switch to Dolby Atmos once the buffer is replaced. Optionally, you can select to restart the video to force the buffer to refresh.
