snd-intel8x0 声卡不响
点播放声音就是不响Corp 82801DB/DBL/DBM(ICH4/ICH4L/ICH4-M) AC'97 Audio Controller
snd-intel8x0
播放测试声音
所有配置都对
不知为什么? 我的声卡是Alc 650 我用的是Fc 3 请先说明你作过虾米配置！ 我的也是阿
原来一直用得好好的自从从2.6.9.x升级到2.6.11.x后就一直不出声了，
我用的是855GME上的集成声卡。

表现为启动和加载模块都正常，但是alsamixer里面 Master和PCM的音量不能调，都是0.

用了一个多月没声音的电脑，今天终于有声音了，
原来是要把alsamixer中的 IEC958 IEC958 C IEC958 C静音掉
