US 2023/0418545 A1 · ELECTRONIC DEVICE AND METHOD FOR RECOGNIZING AUDIO OUTPUT DEVICE CONNECTED TO USB TYPE-C CONNECTOR

Abstract

Embodiments of an electronic device are disclosed. The electronic device may include a USB Type-C connector including at least one configuration channel (CC) pin and a processor operatively connected to the USB Type-C connector. The processor may be configured to: obtain first information of a connected audio output device by using a USB driver; transmit the first information and/or audio card information of the audio output device to an audio framework through a USB framework; control the audio framework to access an interface corresponding to the audio card information; and activate, when at least a portion of second information of the audio output device is obtained through the USB driver while accessing the interface, the interface by transmitting the at least a portion of the second information to the audio framework through the USB framework. Various additional embodiments in addition to the disclosed embodiments are possible.

Dependent claims

An electronic device comprising:

a connector;
a processor operatively connected to the connector;
and
a memory storing instructions that, when executed by the processor, cause the electronic device to:
obtain, in response to connection of an audio output device to the connector, first information related to identification information of the audio output device;
identify whether the audio output device corresponding to the obtained first information exists in the memory;
obtain, if the audio output device corresponding to the first information exists in the memory, second information related to an attribute of the audio output device and audio card information corresponding to the audio output device from the memory;
activate, based on the obtaining the second information and audio card information from the memory, an interface corresponding to the audio card information;
and
transmit an audio signal to the audio output device through the activated interface.
