因linux-2.6.30.4中版本为1.0.20的声卡驱动有bug，在播放音视频时会出现断断续续的现象，所以要用早期版本1.0.18a替换之(可在linux-2.6.29.xxx的内核中提取)。。
#cp -rf /linux-2.6.29.xxx/sound /linux-2.6.30.4/sound    //替换sound目录

#cp -rf /linux-2.6.29.xxx/include/sound /linux-2.6.30.4/include/sound    //替换include/sound目录

#cp -rf /linux-2.6.29.xxx/include/asm-arm /linux-2.6.30.4/include    //复制include/asm-arm目录

#cp -f /linux-2.6.29.xxx/arch/arm/mach-s3c2410/include/mach/audio.h /linux-2.6.30.4/arch/arm/mach-s3c2410/include/mach    //复制audio.h到相应目录

#gedit /linux-2.6.30.4/include/linux/proc_fs.h    //修改proc_fs.h文件，在第70行添加如下内容

struct module *owner;    //因为在sound/core/info.c第159和982行中用到

声卡的驱动已经是1.0.18a了.
Advanced Linux Sound Architecture Driver Version 1.0.18a.
