首先讓我澄清一下，我的立體聲插孔音訊輸出被檢測/列為IEC958/S/PDIF設備，但它不是光纖輸出，而是標準立體聲插孔。這可能已經是問題的原因。
在 Windows 上，插入/拔出檢測工作正常，並且它之前在 Linux 上工作過（使用 Mint 4.10.0-35-generic），但在其他 WM 上，當前使用i3，但我認為它與WM 無關，並且其他內容可能已更改同時。我不記得安裝過任何音訊驅動程序，它已經可以工作了。
問題
我無法觸發音訊插孔插件/拔出事件。
有什麼作用
手動切換pavucontrol到數位立體聲 (IEC958) 輸出 ( iec985-stereo-output) 將使我的揚聲器靜音 ( analog-output-speaker)，並在插孔上提供音訊和音量控制。好的。
清單中沒有其他選項可以為我的插孔提供專有音訊（因此揚聲器靜音）。 （除了我首先處理的另一個問題，直到我發現我必須切換到輸出IEC958：aux 上的音訊音量從 0 到 100（基本上只有開/關）&https://forums.linuxmint.com/viewtopic.php?f=48&t=256467&p=1391958#p1391958但這是一個完全不同的兔子洞）但無論如何。

14、15、16 根本沒有偵測到任何東西。當我將其插入麥克風時，13 確實會觸發，所以至少有一個可以工作。

沒什麼...但是對於麥克風：

差異事件
據我了解，我們可以用以下方式模擬這些事件：
sudo cat /proc/asound/card0/codec\#0 > unplugged
sudo cat /proc/asound/card0/codec\#0 > plugged
diff unplugged plugged
但 diff 沒有輸出任何內容。

Alsa 混音器顯示 S/PDIF 為 0：
pavucontrol 顯示音訊插孔的正確音量
我的 alsamixer 中只有 1 個設備：
哦，當我選擇“模擬立體聲雙工/輸出”時，我無法在Output Devices“揚聲器”下選擇任何不同的端口，我懷疑它應該將音頻插孔列為端口，但事實並非如此。
此外，當打開 cinnamon 音訊設定時，它僅顯示這 2 個作為單獨的音訊來源：

答案1
猜測：BIOS 在插孔的分配上撒了謊，並且您在驅動程式中缺少一個“怪癖”來解決這個問題，或者當您更新時，您遇到了一個不適合您的情況的怪癖。
在 Windows 中，這並不重要，因為預先安裝的驅動程式會忽略 BIOS 資訊並使用正確的（已知）分配。
查看hdajackretask和hdajacksensetest（Debian 等上的軟體包alsa-tools-gui），看看是否可以修復該作業。有關分配的編解碼器內容的資訊可以透過 找到cat /proc/asound/card*/codec\#*。您也可以在此處查看插孔是否已配置為發出「未經請求的事件」（也稱為插頭事件）。
