No DTS, DD, DDPlus, TrueHD, ……

I am having difficulty getting Surround Sound using Jarvis. I am running pc/W10/Jarvis HDMI to Marantz AVR. PC is set to 7.1 output in WASAPI audio and all 7.1 outputs test ok within that. When running Jarvis movies or TV, I only get stereo. KODI displays AAC and 2.0. My 7.1 system only gets the front 2 speaker output and everything I have thought to do has had no effect.

KODI Audio settings:
WASAPI: HDMI – Marantz…/ 7.1/ Best Match/ disabled/ disabled/ Medium/ 1 Minute/ (no 8 ch choice)/ disabled/ Passthru enabled/
Passthru output: WASAPI: HDMI _ Marantz……/ DD enabled/ DDP enabled/ DTS enabled/ TrueHD enabled/ DTS-HD enabled/

I am sure it is something simple, but cannot see it. Please help.
