ELECTRONIC DEVICE AND CONTROL METHOD THEREOF

An electronic device is provided. The electronic device includes a communicator comprising communication circuitry; a speaker; and a processor configured to control the electronic device to: output a first sound via the speaker and control the communicator to transmit a control signal to output a second sound to an external sound output device, receive from an external remote control a first recorded signal obtained by recording the first sound output via the speaker and the second sound output via the external sound output device, obtain information for adjusting output volume of at least one of the speaker or the external sound output device based on the first recorded signal, control the speaker to output a first test sound and the communicator to transmit a control signal to output a second test sound to the external sound output device based on the obtained information, receive from the external remote control a second recorded signal obtained by recording the first test sound output via the speaker and the second test sound output via the external sound output device, and identify an output delay time of the external sound output device based on the second recorded signal.
