Wrapper not working on multiple Q10 units

[napapon 365]

Hi there My name is Napapon
I have three units that have been upgraded to 2.09.  All three will not use the wrapper to play files and as a result, I have no pass-through of digital audio.  All I can playback is stereo.

I have read these forums (and others) top to bottom and have done the following:
-Uninstalled the wrapper and re-installed it (latest version found on this forum). 
-Copied the updated info from Futeko's post into the playerfactory.xml file. 
-Disabled and re-enabled the wrapper. 
-Switched to Kodi Player and switched back to Wrapper Player in the main interface.
-Connected to the Himedia via Samba shares from my PC as well as via a file manager on the Himedia to edit and verify playerfactory.xml
-Enabled auto start in the wrapper app.
-Factory reset on the player. 
-Changed Kodi 17.6 settings for pass-through and enabled 7.1 channel sound (I have a 5.1.2 setup)
-I have read through Futeko's FAQ and I am stumped.  Role back to 2.08 makes no difference.

If I use the built-in media player it works perfectly but then I lose the library functions of Kodi.
I have an Apple TV4 which works with 5.1 / Atmos (IOS12 Beta) so it is not my amp or speaker config etc. ?

An interesting thing I have found is that when I initially went to  /sdcard/Android/data/org.xbmc.kodi/files/.kodi/userdata/ there was no  playercorefactory.xml in the folder.  This was the case even after uninstalling and re-installing the wrapper.

Am I forgetting something?

Thanks in advance.

playercorefactory is a hidden file, so browse to it's location on a PC using Samba and make sure viewing of hidden files is enabled. Is playercorefactory there?

What exactly happens in Kodi when you try to use wrapper? Is wrapper available as an option under 'play using' (press remote menu button when file selected in Kodi).
