我用我的笔记本在移动硬盘上安装fedora9系统，当安装完成后，我从移动硬盘启动，在这个过程中都没有问题。但是启动后，系统没有声音。我用lspci ｜grep “audio”结果没有声卡设备。然后我用lspci查看所有硬件信息。结果如下：

怎么这么多unknown device 阿，另外，怎么找不到声卡设备，显卡也无法识别。我是新手，恭请各位大侠帮忙。

还是没用阿，测试也没有声音，系统－－首先项－－硬件－－音量控制 然后点 编辑－－首先项－－只有volume和in-gain两项，没surround这个选项阿。

如果还是没声音 打开 系统－－首先项－－硬件－－音量控制 然后点 编辑－－首先项－－
选择 Surround 最后关闭就行了 。

打开 系统－－首先项－－硬件－－音效 在－－设备－－标签下全部选 －－自动检测 －－ ，听听－－测试－－声音，这样应该没问题了吧
