ALSA的问题

中庸

我是LFS5.0的系统，编译内核时把声卡支持和ALSA都编译为模块了，alsaconf能正确检测到我 的声卡intel8x0(板载的）这是我加载的模块：
lsmod

执行alsactl时的提示：

执行alsactl store时的提示：
alsactl: save_state:1061: No soundcards found...
[root@lfs ~]# alsactl restore
alsactl: load_state:1134: No soundcards found..
执行 alsamixer的提示：

alsamixer: function snd_ctl_open failed for default: No such file or
