声卡认不出来?不会吧,你什么板子什么声卡啊.

[habao]

在音量控制里面有两个可选设备，C-Media Electronics CMI9761(OSS Mixer)，NVidia nForce2(Alsa Mixer)，我的声卡是nForce2主板自带的AC97声卡

[writetohai]

我的也没有声音，板载声卡（via ac97）和usb声卡都没有声音

[erzhong]

是没有识别声卡，还是混音器(mixer)里设置的是静音／音量为零啊？

lspci里面显示出了声卡信息了吗？lsmod里声卡对应的模块加载了吗？

[louxiabd]

try to shut down iec958 capture monitor in alsa mixer

设备管理 器 里面显示的 是 nForce2 AC97 Audio Controler,在音量控制里面有两个可选设备，C-Media Electronics CMI9761(OSS Mixer)，NVidia nForce2(Alsa Mixer)，我的声卡是nForce2主板自带的AC97声卡

[zhz44]

我的问题和你一样，不过我又换了个Desktop版的 Ubuntu,就解决了。建议下个桌面版，刻张新盘，重新装，格式化重来。一般没问题

[lijzz]

一般应该没问题，如没有声音，你打开音量控制看看，是否里没有打开声音。

[gnix_oag]

也有可能是没有在 相应的 用户组中

[tomqd]

双击右上角的音量控制器，/Edit/preferecnes/把External Amplifermplifer勾上回到刚才双击音量控制器的界面，现在就多了我Switches把里面External Amplifer前面的勾去掉就可以了。

我刚学安装使用KUBUNTU，我的黑金2CANNON版，怎么弄也没声。我在WINDOWS下是AC97和它一起用的。是不是使用KUBUNTU的时候要关掉一个声卡？
