Windows 10 Builds
Note - I've never had this working in Windows 10.
My current Windows 10 version is very far ahead in terms of Builds - see below:
OS Name Microsoft Windows 10 Pro
Version 10.0.18363 Build 18363
If you're suggesting that I rollback, please ensure that you mention the Build version that is working in Windows 10 and that you have tested or seen results for that it is working.
In terms of rolling back Windows 10 Build versions, I am not convinced this will work - as the forum that I posted was from 2015 and that still had issues. So, appreciate if you have a confident version, tried and tested that this is working for, then please
do let me know.
FROM 2015: The issue appears to be well known and around for a while.

FROM 2019: It's definitely to do with the Realtek Audio HD driver - see link below which describes it.. "The sound issues with Windows 10 build 1903 have become more rampant than ever."..,

So over the course of at least 4 to 5 years there has been an issue present.
Manufacturer Build
I've tried the Manufacturers versions - latest version and rolling back to prior versions -especially to get the Realtek Audio HD Manager working. This is not working as I've described previously. The Sound Test is working, but the Playback is failing in
5.1.
