Debian 的最小安装，没有安装声音模块，如何让声音正常工作？

我先对 debian wheezy 进行了最小安装，然后升级到 jessie。安装 wheezy 时，我没有安装任何可选模块。我记得有一个关于声音的模块，但我认为以后可以得到任何必要的模块，所以我没有安装它。

我已经安装alsa alsa-base alsa-firmware-loaders alsa-oss alsa-tools alsa-tools-gui alsa-utils alsamixergui并完全重启。

在 VLC 中，音频->音频设备中列出了三个设备：

Built-in Audio Digital Stereo (HDMI)
Built-in Audio Analog Stereo
Built-in Audio Digital Stereo (HDMI)

我可以通过选择各自的 HDMI 选项来通过显示器获得声音。这有点奇怪，因为其中一个是显示端口，另一个是 HDMI。但是，主要问题是模拟选项不起作用。我插入了可用的模拟扬声器，但没有声音。我测试过扬声器确实可以正常工作，并且没有硬件静音。我还将所有音量条调到最大，alsamixer并确保它们都没有静音。

我要怎么做才能使我的模拟声音正常工作？

答案1

您是否尝试过运行alsamixer并取消静音（M键）并将所有频道的音量推子调高？检查 alsamixer 中每个声卡的音量（F6键）

MM表示该频道在 alsamixer 中被静音。
