I'm getting a bit frustrated already... Did you guys notice that the distortion is directional? You can find one spot that have normal sound if you spin the camera around a bit - one cardinal will have normal sound, the rest will blow your eardrums. Now I'm curious if that "Immersive Spatial Audio" have something to do with this bug.

So far I tested all the "fixes" in all the posts and absolutely nothing works - my game is a fresh install in a fresh win10 and still have it. Any combat action can (and will) cause the issue and sometimes it affects cutscenes.
