That is not where the gong sound comes from. From an electrical engineer's point of view, it is actually more complicated and prone to more failures if you create a separate system to do that, rather than use an audio system designed to readily play from whatever source available, eg. Bluetooth calling. There is no impact as the only thing it is designed to do is play audio. If you have BMW Assist on, it shuts down all music anyway.
