Whether the underlying causes are what LH Mouse says or not, I encounter this constantly. It doesn't take long in a battle in Star Strike for tanks and vehicles to become mute. Most tanks and vehicles have looping movement sound effects (most being rather low priority) and most turreted defensive gun emplacements, as well as some of the big-ass tanks have turret-rotation sounds.
