Netflix and Amazon Video Audio issues!

Hi everyone!

On the AppleTV 4K, both Netflix and Amazon Video suffer Audio issues. On Amazon Video, many titles are only playing in 2.0 Stereo, although they are available in 5.1 Surround and work on other platforms. This problem has been around for more than a year now and still isn't fixed.

Netflix was fine, but since the "Atmos Update" released, all titles with Atmos Sound for the English language version now only play 2.0 Stereo for all other languages. The only way to fix it is to disable Atmos completely and set the ATV to output everything as 5.1 DD.

Amazon and Netflix Support seem unable to even understand that there is a problem. And Apple says it's not their problem. So, is there anything we can do to fix this?
