But i also have an HDMI plugged to my AVR

Ok, I don't see that in your log. It is possible that it is not set up correctly?
You are using the DirectSound version of this... Output Device : default
Whereas I would expect to see the WASAPI version of something like this... Output Device : HDMI - DENON-AVRHD (Intel® Display Audio) (from my log)

Make sure your Windows audio drivers are correctly set up and correctly selected in Kodi settings...
And use WASAPI in Kodi!!!

 

Switched to WASAPI : Correct Output. 

It works ! 

Thank you so much ! (Didn't know about how WASAPI must be the prefered in most cases, usually i use passthrough so i don't care of it )
