在扬声器上播放音乐时我打开 pavucontrol。
点击input Devices、line in、front microphone都rear microphone拔掉了，那么输入设备监视什么Monitor of Family 17h(Models 10h-1fh) HD Audio Controller Analog Stereo？它监视输出设备吗line out？

答案1
在 Pulseaudio 中，每个接收器（音频目标、输出）都有一个关联的源（音频源、输入），称为监视器。
由于某种原因，您的音频硬件提供了一个名为“Family 17h（型号 10h-1fh）”的接收器。这是一个不寻常的名称，可能只是因为您的硬件制造商在 BIOS 中放入了一些通用名称而才会出现。
您没有告诉我们您有什么接收器，所以我假设这只是通用的“内置”接收器（如果您的硬件）可以输出到不同的端口，包括您显示的“线路输出”，可能还有其他端口。
因此，关联的监视器源将镜像您输出到该接收器的任何音频，无论该接收器是否激活了“线路输出”或其他端口。
它与通用输入源（您所说的端口为线路输入、前置麦克风和后置麦克风）无关。
