FIFINE K669B USB 麦克风在 Ubuntu 20.04 上不起作用

我买了一个 FIFINE K669B USB 麦克风。Ubuntu 20.04 能够检测到 USB 麦克风，但是如果我进入 pavucontrol 设置并选择麦克风作为输入设备，它不会检测到任何信号。实际上，它没有显示您可以查看是否有任何输入声音的栏。我也尝试使用其他应用程序（例如 Zoom 或 Discord）使用麦克风，但即使您将麦克风的音量调到最大，操作系统也不会收到任何信号。此外，当系统启动并连接麦克风时，麦克风可以工作。但是，如果在重启后麦克风保持连接状态，它就不起作用了。

使 USB 麦克风在 Ubuntu 上工作的步骤是什么？

干杯
