Abstract
An audio service module is communicatively connected to an audio abstraction module. The audio abstraction module is communicatively connected to a codec driver. The codec driver is communicatively connected to a codec chip. The audio service module receives a headset insertion/removal message and sends the message to the audio abstraction module. The audio abstraction module determines a digital-to-analog converter DAC channel configuration policy in the codec chip based on the headset insertion/removal message, and sends the DAC channel configuration policy to the codec driver. A DAC channel is used to transmit earpiece or headset data, and transmit motor data to a class-D amplifier to drive the motor. The codec driver controls the codec chip to reconfigure the DAC channel based on the DAC channel configuration policy.
