我已经在 HP Stream 14 上安装了 Arch Linux、必要的 WIFI 驱动程序和 XFCE 桌面环境。但是，我无法打开视频音频。我尝试单击屏幕顶部的声音图标，但出现以下错误：
Failed to execute child process pavucontrol (No such file or directory).
我还尝试按物理键盘上的静音/取消静音键，但它没有任何反应。我相信这是我的音频驱动程序的问题，但我没有安装任何驱动程序，因为我不知道要安装哪些驱动程序。lspci终端中命令的输出是

这是我的 WIFI 驱动程序的问题吗？如果是这样，我该如何解决？我应该使用什么命令来安装它们？
谢谢。
