@Ghoulflier Can you test whether this happens in a clean, unmodified installation of the latest official version? Can you test with another HDMI cable? There are several versions of HDMI cables (1.1, 1.2, 1.3, 1.4, 2, 2.1), do you know which one you are using? Can you test it on another TV? Maybe this will help you: https://forums.libretro.com/t/bad-cracking-stuttering-sound-in-ra-with-any-system-or-game-with-vsync/15886
