Modify AC'97 audio front adapter to HD audio. 修改计算机AC'97前音频面板接口至HD音频接口

If your computer case is legacy type and has a front audio panel with AC'97 interface, but your main board audio interface is HD Audio standard, you can buy a front audio panel with HD audio interface that only cost $1 maybe, but you can also modify your AC'97 panel to HD Audio interface.

You need electric iron and multimeter if you wanna DIY it, and after modify, computer always think your earphone and/or microphone plug in to front of computer case (can not detect the status of front audio panel correctly).

All connections are shown in the pic below.

如果你的电脑机箱是老式的，有一个AC'97接线规格的前音频面板，而你的主板上的音频接口是HD音频的，那么你可以花一美元购买一根HD音频接口线，或者动手修改AC'97面板至HD音频接口面板。

如果想自己动手修改那你需要电络铁和万用表，并且经过修改后，计算机会始终认为你将耳机或麦克风插入到了机箱前面板的接口中（不能正确检测前面板接口的状态）。
