我有一個 Arozzi Sfera 桌上型麥克風。它的背面有一個耳機插孔，我認為是一個顯示器。
連接麥克風後，我可以看到設定視圖的「聲音」標籤中列出的各種音訊輸出設備，包括我的藍牙耳機、與顯示器的 HDMI 連接和麥克風。當我選擇任何輸出設備並使用“測試”功能時，音訊會定向到麥克風的耳機插孔。
我嘗試運行pulseaudio -k，但當systemctl --user restart pulseaudio.service問題出現時，卻無濟於事。

依編號卸載 alsa-card 模組（pactl unload-module 8在本例中）也會停用麥克風作為輸入。
pactl info告訴我預設接收器是bluez_sink.2C_4D_79_40_C5_3B.a2dp_sink.當我從設定中更改音訊輸出時，情況會改變。
一個可能相關的問題是，當我斷開並重新連接麥克風時，我可以將麥克風視為音訊設定中的「預設」輸出。
另一個觀察；當我在應用程式的設定中明確設定音訊接收器時，例如在 Discord 桌面應用程式中，它就可以運作。似乎只有預設接收器和/或 gnome 才會表現出這種行為。
今年3月底左右，這種行為似乎已成為常態。我知道30號它工作正常。我唯一的解決方法是拔掉麥克風。
我想知道如何解決這個問題。如果做不到這一點，我想知道如何診斷這個問題，以便我可以向正確的一方提交錯誤報告。
答案1
我相信我已經找到了解決方案。使用pavucontrol，我找到了麥克風的音訊配置文件，為其配置的配置文件是“數位立體聲輸出+單聲道輸入”，這讓pulseaudio感到困惑。我相信這是iec958-stereo+input輸出配置檔。
將其更改為“單聲道輸入”（我認為是mono-fallback）解決了問題。
