如何启用我的华硕 Xonar DGX（CMI8788 芯片组）声卡？

我一直在努力尝试我的声卡在 Linux 下工作，从命令行它报告如下：

user@desktop:~$ sudo lspci -v | grep -A7 -i "audio"

经过一番检查，我发现虽然系统似乎识别了它，但 alsa 似乎没有将其识别为音频设备。我已经尝试过重新编译相关模块但我还是不太走运。另外，根据版本和内核，它应该可以开箱即用，所以为什么它不能正常工作就有点神秘了。

答案1

我通过在终端中打开 alsamixer 并将输出设置为多通道来解决这个问题。

然后重新启动并在 Ubuntu 声音设置中选择正确的设置。现在一切正常:)

答案2

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，你需要内核 3.5 或更高版本最近的快照alsa-driver 包。

答案3

有人建议输入alsamixer控制台，然后按F6，选择 Xonar 作为声卡，然后有“模拟输出”之类的开关，你可以将其从“前面板”更改为后面的开关。这对我很有帮助。
