Since the audio chip supports High Definition Audio Specification, the function of each audio
jack can be defined by software. The input / output function of each audio jack listed above
represents the default setting. However, when connecting external microphone to the audio port,
please use the Line In (blue) and Mic In (Pink) audio jack.
