Abstract: An electronic device may include a processor, a communication module to establish a wireless link with an output device, and a transmit buffer in which an audio packet to be transmitted to the output device through the wireless link is stored. The processor may be configured to control the communication module to transmit an audio packet, which is encoded at a first bit rate, stored in the transmit buffer to the output device, to store, in the transmit buffer, an audio packet, which is encoded at a second bit rate lower than the first bit rate, when a state of the transmit buffer fails to satisfy a threshold condition, and to control the communication module to transmit the audio packet encoded at the second bit rate to the output device.
