Force Kodi to passthrough DTS?

Hi,
I have an issue with DTS sound on movies.
Here is the setup I have:
Sony Bravia TV with Android –> HDMI with ARC connect –> Yamaha RX-V775 –> HDMI connect –> Surface Pro (first generation)

Now, when I start the Surface with this connection setup the sound device inside windows points to the Sony TV. However it appears that Kodi thinks that the TV cannot understand DTS, so the passthrough option for DTS is not visible. When I switch off the TV the sound device in windows changes to my Yamaha receiver and Kodi shows the DTS option. When using a different media player the sound sent to the receiver (even with the TV on) is proper DTS HD, so basically the setup does work. However when using Kodi the receiver only gets DTS.

I am simply at a loss as to what I might need to change in order to get this to work the way I want it. Is there a way to force Kodi to always pass through all sound no matter what? Or does anybody have a suggestion on what to change in the setup? Using Kodi on the TV is not an option, DTS doesn’t properly work in Kodi there either and the normal video player on the TV cannot properly handle 20:9 videos without stretching them to 16:9 (a know bug in Sony TVs apparently)

I tried searching for a solution but honestly I am no sure what to search for exactly and there are so many different DTS issues that it’s hard to find anything specific.

Ah damit, just saw that this is posted in the wrong forum. Sorry got confused about the lock icon in the ‘General Support’ forum. Could an moderator please move the post to the Windows support forum?

Again sorry Sad
