Question Surround sound issue with Windows 10 ?

[Tomeyyy]

Hello,
I have a Asus Rog gaming pc (which should have surround capabilities?) aswell as a RME Fireface 802 soundcard and a Room correction device.

I upgraded my setup to a 5.1 Dynaudio LYD 5 recently and wanted to use the ADAT connections to make it happen.

Bascially : Windows 10 computer >USB> RME Fireface 802 >ADAT out 1> Trinnov NOVA> Speakers.
On the Manage sound devices on Windows, i have ADAT 1 (1+2)/ ADAT 1 (3+4)/ ADAT 1 (5+6) as stereo pairs. They all work separately as a stereo pair but, i do not have ADAT 1+6 for surround channels?! So, i'm wondering if it's something that i did not configure properly...

On totalmix FX (which is the routing matrix for the computer using RME software), i am able to route the ADAT 1+2 channels on the remaining surround channels and they all output properly.
Here is a picture of the Windows outputs. Here is a picture of the routing matrix of the RME software just in case

Any ideas?

EDIT: Seems like i was able to figure it out in the routing matrix of the RME software
