今天参考 天嵌科技出品-Linux移植之Step By Step_V4.5_20100605.pdf 的step17 移植声卡驱动，
我的内核是linux-2.6.32.60的，
第一次从linux-2.6.29.tar.xz获取的1.0.18a的声卡驱动，其他部分完全参考手册，
这个过程中出现两个错误提示
error: implicit declaration of function 's3c2410_gpio_cfgpin'
解决办法参考
Sound/soc/s3c24xx/s3c24xx-i2s.c:407:error:implicit declaration of function ‘s3c2410_gpio_cfgpin’在2.6.31内核中，s3c2410_gpio_cfgpin是在include/linux/gpio.h中定义的，要添加这个文件在sound/soc/s3c24xx/s3c24xx-i2s.c中，第24行添加：#include <linux/gpio.h>

参考解决办法
sound/soc/s3c24xx/s3c24xx-pcm.c:429: warning: 'DMA_nnBIT_MASK' is deprecated
make[3]: *** [sound/soc/s3c24xx/s3c24xx-pcm.o] Error 1
make[2]: *** [sound/soc/s3c24xx] Error 2
make[1]: *** [sound/soc] Error 2sound/soc/s3c24xx/s3c24xx-pcm.c中的S3C2410_DISRCC_INC等常量没有定义，s3c2410_dam_config函数的参数个数不对原因是2.6.31内核中dma相关的文件改变了，以前的跟dma有关的代码就不能使用了，我们只需把原来代码中的sound/soc/s3c24xx/s3c24xx-pcm.c这个文件替换回来就可以了。继续编译，就可以正常编译了，可以正常放音录
通过上面的办法成功解决问题，但下载后测试，却只有很刺耳的声音，这是怎么回事，

可以录音，但播放的时候还是有杂音 ，隐约能听到录制的声音，这个杂音是咋回事，怎么解决呢？求大神
第二次尝试是从linux-2.6.30.4_20100531.tar.bz2 得到的声卡驱动 问题依旧
