Xbox Series X Öbb 1116 “taurus” Sound Problem

Hi,
Can someone help me? I'm driving the ÖBB 1116 Taurus on the way and unfortunately it has happened several times that the locomotive's solmization sound disappears and ceases to exist. It only works again if I save the game and re-enter it. Has anyone found a solution to this? Thanks in advance.
