首先让我澄清一下，我的立体声插孔音频输出被检测/列为IEC958/S/PDIF设备，但它不是光纤输出，而是标准立体声插孔。这可能已经是问题的原因。
在 Windows 上，插入/拔出检测工作正常，并且它之前在 Linux 上工作过（使用 Mint 4.10.0-35-generic），但在其他 WM 上，当前使用i3，但我认为它与 WM 无关，并且其他内容可能已更改同时。我不记得安装过任何音频驱动程序，它已经可以工作了。
问题
我无法触发音频插孔插件/拔出事件。
有什么作用
手动切换pavucontrol到数字立体声 (IEC958) 输出 ( iec985-stereo-output) 将使我的扬声器静音 ( analog-output-speaker)，并在插孔上提供音频和音量控制。好的。
列表中没有其他选项可以为我的插孔提供专有音频（因此扬声器静音）。 （除了我首先处理的另一个问题，直到我发现我必须切换到输出IEC958：aux 上的音频音量从 0 到 100（基本上仅开/关）&https://forums.linuxmint.com/viewtopic.php?f=48&t=256467&p=1391958#p1391958但这是一个完全不同的兔子洞）但无论如何。

差异事件
据我了解，我们可以用以下方式模拟这些事件：
sudo cat /proc/asound/card0/codec\#0 > unplugged
sudo cat /proc/asound/card0/codec\#0 > plugged
diff unplugged plugged
但 diff 没有输出任何内容。

我的 alsamixer 中只有 1 个设备：
哦，当我选择“模拟立体声双工/输出”时，我无法在Output Devices“扬声器”下选择任何不同的端口，我怀疑它应该将音频插孔列为端口，但事实并非如此。
此外，当打开 cinnamon 音频设置时，它仅显示这 2 个作为单独的音频源：

答案1
猜测：BIOS 在插孔的分配上撒了谎，并且您在驱动程序中缺少一个“怪癖”来解决这个问题，或者当您更新时，您遇到了一个不适合您情况的怪癖。
在 Windows 中，这并不重要，因为预安装的驱动程序会忽略 BIOS 信息并使用正确的（已知）分配。
查看hdajackretask和hdajacksensetest（Debian 等上的软件包alsa-tools-gui），看看是否可以修复该作业。有关分配的编解码器内容的信息可以通过 找到cat /proc/asound/card*/codec\#*。您还可以在此处查看插孔是否配置为发出“未经请求的事件”（也称为插头事件）。
