One area where many Google TV streaming devices fall short is support for lossless audio passthrough, such as Dolby TrueHD, DTS-HD, and DTS:X surround sound. This is especially true for budget-friendly devices, such as Walmart's existing Onn streamers, none of which support lossless audio formats.

Amazon is pushing a new software update to the 3rd-gen Fire TV Cube that should make video and audiophiles happy. Software version 7.6.1.3 (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.
