Multi Speakers System
The CMedia 8738 Audio subsystem provides 3 wave channels (front/rear/

sound sources to the listener's back, the two rear speakers will work to enhance
the rear audio positional effect, so as to complement the insufficiency of using
only two front speakers to emulate the audio effect.
