Audio Interface

The audio interface provides two kinds of audio output choices: the FrontAudio
and the RearAudio. Their priority level is as sequence. When the FrontAudio is
available, the RearAudio will be cut off. When the FrontAudio is absent, Pin5 and
Pin6, Pin9 and Pin10 must be short connected.
