Okay, so the main problem is that the Spatial Audio is not working.
Firstly :
I Have just enabled the THX Spatial audio thing, but i cant feel any differences. So, after a few while, i think to my self "Maybe that clearly visible Yellow-Orange triangular error sign is something that i need to worry about"
So i pressed the warning triangle thing, but then this appears :

When i press "Use This Device Instead" Nothing will happen. Like, literally nothing.
After a few moments, i have decided to Disconnect & Reconnect the Soundcard from my PC.
To my surprise, it worked!

i then checked the "Mixer" Tab to re-enable the THX Spatial audio
Keep in mind : that im listening to music in Spotify as im Enabling the Spatial Audio.
After ive enabled the spatial audio thing, i still couldnt see/feel the differences
So yeah, thats the problem. (Ive also tried to play Rainbow6S while it is on but i still cant feel the differences)
