modules的管理

事情的缘起是因为编译了三汇的语音卡驱动和编解码卡驱动，在加载编解码卡驱动的时候

果然没有加载zttranscode; google的结果是这个模块是asterisk为硬件音频编解码的一个接口；如此重要的东东竟然默认是没有加载的，天理何在

我用脚后跟都能想得到模块文件在哪里；呵呵

insmod zztranscode

然后再进入

/usr/src/zaptel-1.4.8/cdcx522apci-1.0.0

insmod shcdc.ko

竟然OK了，鬼哭狼嚎；这下可以用来，555；拨打测试了下，貌似没有想象中CPU占用为0的迹象，3路并发在3.0%左右；
