Problems w HD audio in Kodi

I am frustrated here. Here is my setup
I have a souncard that supports HD audio and it works passing through audio to my Marantz Sr 6009 in other setups
So I have hdmi running from computer into avr, avr out to 4k suhd tv
My Kodi settings
Both audio and passthrough settings are Wasapi HDMI Marantz
No of channels 2.0(I have tried other settings too)
Passthrough enabled and all HD audio boxes checked
Output config Best match and I’ve tried the other 2
Resample quality: Medium

Everything is correct in all of the reading I’ve done but still wont get HD audio. Hopefully I’ve missed something that somebody can find here??
Using Kodi 16.1
