Abstract: An electronic device includes: an Application Processor (AP) including a CPU; and an audio processing unit configured to: receive an audio stream of M channels from the CPU, convert the M-channel audio stream into an N-channel audio stream, the N-channel being different from the M-channel, output the N-channel audio stream through an output device. The audio processing unit is further configured to: detect a connection with the external electronic device through an audio output interface; determine whether to stop the converting the M-channel audio stream into the N-channel audio stream, based on information received from the CPU; and transmit, via the audio output interface, the M-channel audio stream to the external electronic device in response to the determination of stopping the converting the M-channel audio stream into the N-channel audio stream.
