Hi, as per the title, I have the latest and a previous version of Amazon Cube, and as reported, the Atmos sound doesn't work on ANY streaming application. It doesn't work on the self test under settings, either. By reading Amazon's support page apparently this is happening because the TV I'm using is not recognised as 4K HDR but as a 4K SDR tv. I confirmed this by connecting a Vizio TV, which doesn't work, and a Samsung TV, which does work. So the question I have is whether there's a workaround to this Amazon Cube limitation? Has anyone tried using a 4k HDR splitter or something else that can allow for the atmos sound to be output from the cube? (I know this is an awful limitation of an Amazon Cube, especial for projectors since not many of them are 4k and one would have to upgrade if one wanted Atmos sound!) Any other ideas for a workaround? Both cubes have the latest firmware, great cables, i tried different inputs etc. As mentioned the known problem is that the Amazon Cube doesn't recognise one of the TV s as 4k HDR, but as 4K SDR. This is really silly limitation but I guess that's a different issue and i just want a workaround. Thanks!
