经过一番努力，终于将CS4334音频驱动移植到了开发板上，下面是驱动程序和测试程序的源代码。这里有个问题，希望各位大侠能够给予指点。就是播放小文件时，效果还不错，但文件大于1M时，就出现了问题，搞不清楚为什么。

-After some efforts, finally CS4334 Audio Driver transplanted to the development board. Below are the driver and testing procedures of the source code. Here is the problem, hoping to Shanhaiguan to give guidance. Broadcast is a small paper, the results were pretty good, but more than a paper M, we have the problem, not sure why.
