One of the devices, that is a root device, stores system information on each audio device, and periodically transmits the system information to the audio apparatus. Each audio apparatus, when having received system information, returns an ACK to the route device. The root device determines the existence of reception of an ACK from respective audio devices; and, when no ACK has been received from any audio device of the audio devices, updates the system information by performing rewriting so that the audio device is non-active.SELECTED DRAWING: Figure 1
