症狀
我聽不到任何聲音。
在設定應用程式的「聲音」標籤中，我可以選擇這些裝置：
HDMI / 顯示埠 - 內建音頻
數位輸出 (S/PDIF) - 內建音訊
耳機 - 內建音頻
虛擬輸出
當我在其中任何一個上單擊“測試”時，沒有可以單擊的揚聲器。我希望出現向左和向右按鈕。
更新1
當我從命令列以詳細模式啟動pulseaudio時，它會在幾秒鐘後快速終止：
I: [pulseaudio] core.c: We are idle, quitting...
I: [pulseaudio] main.c: Daemon shutdown initiated.
以較大的空閒逾時啟動pulseaudio，給出相同的結果：沒有音訊輸出，對話框中沒有揚聲器。
更新2
發生此問題時，重新啟動可暫時修復該問題。
我嘗試在透過暫停/喚醒週期重新啟動後觸發該問題，但喚醒後，聲音仍然有效。因此，觸發它需要的不僅僅是暫停。
