So i have bought a new gaming pc but there was this constant noise in my headset. I tried a diffrent headset but it was still there. Im sure its from the computer. when i turn up the volume on the computer it has no effect on the sound but when i turn it up on the headset it gets louder. (I know it sounds like its the headset but it isnt). Now i wanna stream and record videos but this sound makes it to the recordings and streams as well. Does anyone have an idea? Hope you can help me :)
