Can you hear it? Prime TV app suffers Dolby 5.1 audio loss

If you’re looking to watch Amazon Prime TV movies in Dolby 5.1 sound through your Apple TV, be ready for a disappointment.

Overnight into Thursday, movies through the new Prime TV app that showed a description of audio available in the Dolby 5.1 format – such as the 007 movie ’Spectre’ and the series ‘The Grand Tour’ – are now missing that description. As a result, content can only be heard in two-channel stereo.

Tests conducted by in the last 24 hours confirm various reports of the lack of Dolby 5.1 support. When configured with an Apple TV 4K unit and a 7.1 stereo system, audio is only being fed to one speaker and a subwoofer.

A test of audio capabilities on a second-generation Amazon Fire TV device showed full 5.1 sound support, unlike through the tvOS app. The audio issue is not affecting 4K and HDR video content from the service.

The lack of Dolby 5.1 support is an immediate disappointment for owners of the Apple TV 4K unit, which is capable of delivering 4K, HDR, Dolby Vision and 5.1 sound. This capability is not an issue with other applications, such as iTunes and Netflix.

Apple TV owners on Reddit are reporting the same issue with surround sound with others explaining the problem is not happening through the Prime Video app on other devices like game consoles, and specifically the Sony Playstation 4.

Amazon, through its @AmazonHelp Twitter account, says the company is investigating the matter.
