Embodiments of this application provide a method for detecting a connection to a headset port of an electronic device, an electronic device, and a readable storage medium. When a headset component is connected to the headset port of the electronic device, if it is detected that the electronic device does not have a function of performing conversion between digital audio and analog audio and that the headset component connected to the headset port of the electronic device is an analog component, it is determined that the headset port cannot support the connected headset component. In this way, an electronic device omitting a codec can determine that an analog headset cannot be used.

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.
