Razor Blackshark USB card not controlling volume through windows mixer.

Hello! I recently adquired the razor blackshark v2 (the one that uses de USB card). The issue is that if i use it without the f-ing Windows Sonic for Headphones i cant control the volume of other programs from the mixer, which makes it really uncomfortable to use when speaking with others through voice chats like discord. The only way to control the volumes is using Windows Sonic, but that messes up the THX spatial sound and makes it sound like sh*t. Has anyone encountered the same issue? Ive been searching for hours and cant come with a solution :(
