Audio location glitch for vehicle

Occasionally, a truck with a gun will glitch so that it sounds like the truck's gunfire is coming from a different location on the map.

@nfearnley I encounter this often the sound of the gun fire comes from where the truck was spawned and not where the truck actually is. In other words I respawn to loud MG gun fire with truck nowhere in sight and then when I find the truck and the person shooting said MG there is no sound coming off the trucks MG lol.
