Original Abstract Submitted
An electronic device and a control method thereof is provided. The electronic device control method may include receiving audio data and data on the audio data including a presentation time stamp information indicating when the audio data is required to be output, and a time stamp information of an external device; synchronizing a system time of the electronic device with a system time of the external device by using the time stamp information of the electronic device and of the external device; storing the audio data in a buffer based on the system time of the electronic device and the presentation time stamp information; outputting the audio data stored in the buffer by a first audio clock through a speaker of the electronic device; and changing the first audio clock by comparing the audio data stored in the buffer with a predetermined buffer amount.
