最近用Tiny2451移植一个ALSA声卡，用的是友善Tiny2451A_20140116光盘的内核及文件系统 ，声卡芯片是WM9714
参考：
http://www.linuxidc.com/Linux/2014-02/96931.htm 然后编译、烧写。内核打印信息有
[ 2.735000] soc-audio soc-audio: ASoC machine SMDK WM9713 should use snd_soc_register_card()
[ 2.965000] soc-audio soc-audio: wm9713-hifi <-> samsung-ac97 mapping ok
[ 3.130000] ALSA device list:
[ 3.130000] #0: SMDK WM9713
但测试还是没声音，出现cat: write error: Input/output error
[root@FriendlyARM /]#
cat /dev/urandom > /dev/dsp
[ 170.605000] mapped channel 12 to 0
cat: write error: Input/output error 网友建议在ac97初始化的时候，设置wm9714相关为喇叭输出功能，但添加了wm9714喇叭输出设置还是一样有问题
望高手们指点一下，谢谢！！
