如何启用我的华硕Xonar DGX（CMI8788芯片组）声卡？
我一直在努力让我的声卡在Linux下工作，从它报告的命令行如下：

snd-oxygen模块似乎正在加载correclty， sudo modinfo snd-oxygen报告如下：

查看http://www.alsa-project.org/main/index.php/Matrix:Vendor-Asus ; 看来你的内核太旧了。
对于Xonar DGX，您需要内核3.5或alsa-driver软件包的最新快照 。
我通过在终端中打开alsamixer并将输出设置为多通道来修复此问题。
然后重新启动并在Ubuntu声音设置中选择正确的设置。 现在全部工作:)
有人建议在控制台中输入alsamixer ，然后按F6 ，选择Xonar作为声卡，然后有“模拟输出”之类的开关，你可以从“前面板”改为后面的那些，例如。 这对我有所帮助。
