Good day to all! I apologize for my English, I use machine translation.
During the fight, the sound is very hoarse and distorted. And that's what I found. Distortion occurs when the camera is behind the character. When I move the camera to the character's face, the distortion disappears and the sound works as it should. AMD FX-8320e processor.
I attach a video demonstrating this. In the video, I use the same skills, both from the back and in the face. Maybe this information will somehow help technical support.
