I'm still trying to get what was a working installation working again. Reverted back to Widows 10 1809 without any updates. Didn't run the Intel driver update. Got Dolby Access to install and be supported properly. 3D works with the Kodi 18.1 fork. Audio will NOT passthrough. Bitstreams as PCM only. VLC supports full audio passthrough of both Dolby Atmos and dts:X (plus all imbedded/lower codecs). I've not tried to install the RealTek driver over Dolby Access but I'm not sure that will work. Frustrated and out of time for the night.

Reading your previous comments, I would
Assume that you had tried the following:
1) unplug and plug the receiver power (seriously!)
2) verified your receiver fw to be latest
3) checked that playing YouTube/vimeo/Spotify from the computer yield audio in receiver (stereo)
4) tried to play simple stereo audio via kodi
5) enabled expert mode in kodi and set the audio to WASAPI receiver output for both passthrough and regular audio
6) set the speaker system to 7.1(or whatever setting you use) in kodi
7) disabled AC3 transcoding and enabled all other passthrough mode

All of that has been done. The receiver shows Atmos and dts:X when playing through VLC. Kodi is just PCM for an audio codec. Intel Display Driver is installed. Dolby Access allows selecting Dolby Atmos for Home Theater. Before I rolled back to Windows 10 1809 and had it fully update the Dolby Access got Atmos working with Kodi (as well as all other passthrough audio) but there was no 3D support from Windows.

All of this worked a few weeks ago before the main hard drive SSD blew.
