Sound treatment method of notebook computer

A sound processing method for notebook computer in order to support multiple sound modes includes judging if the set-up sound mode is stereo, defining that the speaker interface is dual-channel output and microphone interface is sound input if it is, or judging if it is 4 channels or 5.1 channels if it is not, defining that the microphone interface is sound pre-output and the speaker interface is surround sound output if it is 4 channels, or defining that the microphone interface is mid-frequency sound outupt in bass, the speaker interface is surround sound output and built-in speaker is front sound output if it is 5.1 channels. 一种笔记本电脑的音响处理方法，以支援多种音响模式。首先判断所设定的音响模式是否为立体声，若是则限定喇叭接头为双声道输出端，限定麦克风接头为音响输入端。若音响模式非立体声，便接着进行4声道或5.1声道的判断。若音响模式为4声道，则限定麦克风接头为前置音响输出端，限定喇叭接头为环绕音响输出端。若音响模式为5.1声道，则限定麦克风接头为重低音壁置中音响输出端，限定喇叭接头为环绕音响输出端，内建喇叭为前置音响输出。
