Sound bu - map Japan - Airfield

Hello everyone,
i think this was an issue resolved a few months ago with a patch but… while in Japan map, in 3rd person view the engine sound of the plane sounds like its underwater, specifically while on the airfield in the north on the map.
Sound get normal when u get past 1800 meters of altitude. In cockpit view i did not have this problem
Anyone else having this issue? (again?)
