我使用的是运行 Arch Linux 的 Alienware M16，并且安装了 Pipewire，并且有 2 个可用控制器，一个由 Nvidia 显卡控制，一个由 AMD 音频控制器控制。通过电缆将外部耳机连接到耳机插孔可使麦克风工作，但当未连接外部耳机时，内部麦克风仅记录静态噪音，并且不会对任何外部刺激做出任何反应。

这就是 qpwgraph 的样子： qpwgraph 设置
我尝试重新安装 Pipewire，还尝试摆弄 qpwgraph，似乎音频捕获不起作用，但它确实连接到了 Audacity 和 Zoom 语音引擎等应用程序的输入。我什至尝试使用命令
pactl set-card-profile alsa_card.pci-0000_09_00.6 output:analog-stereo+input:analog-stereo你有没有设法解决这个问题，如果是的话，如何解决？
