Electronic device for controlling audio output and operation method thereof

A method of operating an electronic device, the method comprising:

• receiving a first user input to determine a main output device and a sub output device, wherein the sub output device is selected as an output device for a certain application;
• displaying a default path list and a separate path list, wherein the default path list comprises a first object of the main output device, and the separate path list comprises a second object of the sub output device;
• and
• outputting a first audio data through the main output device, and a second audio data of the application through the sub output device,
• wherein the first audio data comprises audio data other than audio data generated by at least one application included in the separate path list.

An electronic device comprising:

• a display;
• a communication interface;
• at least one processor;
• and
• a memory operatively connected to the at least one processor,
• wherein the memory is configured to store instructions, that, when executed, enable the at least one processor to perform:
• displaying an audio device list comprising identification information of a plurality of audio output devices comprising a first audio output device,
• when the first audio output device is set as a main output device and a sub output device, displaying, with identification information of the first audio output device, a first object representing that the first audio output device is selected as an audio output path,
• when the first audio output device is set as the main output device, displaying, with the identification information of the first audio output device, separate button icon and a second object representing that the first audio output device is selected as a default audio path, and
• when the first audio output device is set as the sub output device, displaying, with the identification information of the first audio output device, main button icon with a third object representing that the first audio output device is selected as a separate audio path.
