我已經在 HP Stream 14 上安裝了 Arch Linux、必要的 WIFI 驅動程式和 XFCE 桌面環境。我嘗試單擊螢幕頂部的聲音圖標，但出現以下錯誤：
Failed to execute child process pavucontrol (No such file or directory).
我還嘗試按實體鍵盤上的靜音/取消靜音鍵，但它沒有任何反應。我相信這是我的音訊驅動程式的問題，但我沒有安裝任何驅動程序，因為我不知道要安裝哪些驅動程式。lspci終端機中命令的輸出是

這是我的 WIFI 驅動程式的問題嗎？如果是這樣，我該如何解決？我應該使用什麼命令來安裝它們？
謝謝。
