Claim 0:
1. An audio signal synchronization control device, comprising:
a host controller;
a plurality of audio devices;
a communication unit capable of performing broadcast communication, having a device control address separately set for the plurality of audio devices and a synchronization address common to the plurality of audio devices, and configured to control the plurality of audio devices from the host controller; and
a clock oscillator that supplies a clock of a same source oscillation to the plurality of audio devices as a master clock,
wherein the host controller performs the broadcast communication with the plurality of audio devices using the synchronization address, and
each of the plurality of audio devices comprises:
a synchronization control unit that generates a synchronization reset signal in a case where the broadcast communication is performed with the synchronization address;
a clock reset control unit that generates a timing signal in response to the synchronization reset signal generated by the synchronization control unit; and
an audio signal processing unit that processes audio data in accordance with the timing signal generated by the clock reset control unit.
