Method for switching audio channels and media play system

The invention provides a method for switching audio channels and a media play system. The method comprises the following steps: when a Bluetooth control device sends an audio channel switching instruction to a Bluetooth media output device by an audio video remote control profile (AVRCP) protocol, the audio channel switching instruction is contained in the custom filed of manufactures of the AVRCP protocol, the Bluetooth media output device outputs a corresponding audio signal after receiving the audio channel switching instruction through the AVRCP protocol. According to the invention, the Bluetooth media output device can be remotely controlled by Bluetooth in a wireless manner so as to switch the audio channels for playing multimedia programs, thereby ensuring that users can freely select and pick up dubbing language types.
