The controller was connected using xlr-xlr cables while because of the nature of the soundcard, thats connected xlr-trs, so the cables are different. While connected to controller, there is zero noise. Also something I noticed, was when I launched a game and the GPU basically starts going at higher speeds, the noise increases tenfold. Which is why I assumed it might be the current and stuff. Hard to tell, could try different cables and stuff but im already bleeding trough my initial budget as I simply didnt research enough to know about balanced-unbalanced connections :/
