ABSTRACT:
A method for processing sound effects in a notebook computer to support several sound effect modes. First, the method determines whether or not the pre-assigned sound effect mode is the stereo mode, assigns a line-out jack as a dual-channel output terminal and assigns a Mic-in jack as a sound-effect input terminal if the sound effect mode is the stereo mode. If the sound effect mode is not the stereo mode, a 4-channel or 5.1 -channel determination is made. If the sound effect mode is the 4-channel mode, the Mic-in jack is assigned as an output terminal for front sound effects, and the line-out jack is assigned an output terminal for surround sound effects. If the sound effect mode is the 5.1-channel mode, the Mic-in jack is assigned as an output terminal for woof and center sound effects, the line-out jack is assigned as an output terminal for surround sound effects, and the build-in speaker is assigned as an output for front sound effects.
