我已经为此工作了一段时间，但还没有任何进展。
我有一台 MSI GS60 Ghost Pro（Skylake），配备 Realtek ALC898 音频芯片组。
这台电脑有点奇怪的是它有四个扬声器：两个大的前置扬声器和两个小的后置扬声器（从技术上讲，它们是独立的线路）。问题是，在 Linux 中，耳机似乎直接连接到后置扬声器线路。
在 alsamixer、pavucontrol 或 kmix 中也无法检测到耳机。
我曾经hdajackretask强制启用任何可以设置为耳机输出的东西，如果我将音频配置文件设置为Analog Stereo Duplex，应用程序做看到耳机插孔，但它始终“未插上”，因此自动切换不起作用。
在 4.0 环绕声配置文件中，此解决方法无效，但我就是这样发现耳机插孔正在镜像后置声道的。
我尝试过尝试各种 pulseaudio 配置和开关，也尝试过清除这些配置并重置。我尝试过安装官方 Realtek 驱动程序，但由于它们是 2014 年的，所以无法编译。
这是Ubuntu 18.04，但是17.10和17.04上也存在同样的问题。
以下是一些信息（告诉我还要运行什么）：
