I bought a new Logitech headset (G332 SE, jack) today and when I play Minecraft there's a kind of noise in the background, which changes in sound when I move or do other things. As soon as I close it, it's gone.
So did you try Google or YouTube on the Internet? What I could imagine is that you need to update some driver or your headset has a manufacturing defect or there's something wrong with the game. K.a. There can be so many things.
Thanks, do not know exactly what the problem was, anyway it is gone now
