Amazon is pushing a new software update to the 3rd-gen Fire TV Cube that should make video and audiophiles happy. Software version 22.214.171.124 (PS7613/3686) is currently rolling out to devices with improvements to the Super Resolution Upscaling feature that should make non-4K content look even sharper. The update is also adding a feature that has long been requested by surround sound enthusiasts, which is support for DTS, DTS-HD, and Dolby True HD audio passthrough.
Super Resolution Upscaling is a feature that is unique to the 3rd-gen Fire TV Cube and is Amazon’s answer to Nvidia’s AI Upscaling feature on the latest Shield TV and Shield TV Pro. Both upscaling features are supposed to go beyond standard upscaling to make lower-resolution video look even better on 4K TVs. While Nvidia’s advanced upscaling results in a noticeable change compared to standard upscaling, the Fire TV Cube’s advanced upscaling seemed to make little to no difference. This latest software update is supposed to improve things. Stay tuned for an upcoming article from me comparing the Cube’s new upscaling to the Shield TV and detailing whether or not the update has made a difference.
In addition to upscaling improvements, as mentioned, Amazon has added support for DTS, DTS-HD, and Dolby True HD audio passthrough. Support for these lossless surround sound formats has long been missing from Fire TV devices. Fire TV devices have supported several Dolby formats with onboard decoding for a long time, but these more advanced formats have been missing. That finally changes with the latest software update currently rolling out. You won’t find any new audio settings to enable or disable, but the aforementioned audio formats should be passed through automatically when used.
Amazon has confirmed to me that both of these new video and audio improvements are included in the version 126.96.36.199 (PS7613/3686) software update that is currently rolling out to devices. Amazon says the update should be available to all 3rd-gen Fire TV Cube owners by the end of the week. I’m unsure if other Fire TV models will also receive support for the new audio passthrough formats. I’ve asked Amazon for clarification and will update this article if I receive a response.
