pactl unload-module 23但是，通过应用程序禁用内置扬声器后，microsoft teams会显示无法检测到麦克风的消息。
列出了耳机的 USB 麦克风：
“移除”内置扬声器后，声音可以正确传到耳机——但麦克风无法接收。
之前禁用内置扬声器，其他voip应用程序运行良好。现在，除了microsoft teams，textnow网站似乎找不到麦克风。
这款耳机在另一个盒子上运行良好，这个盒子也可以运行，21.04但缺少一个能够播放音乐或其他声音的内置扬声器，我想，HDMI就像第一个盒子一样。
也可以看看：

感谢 IRC 上的 damo22。
我不知道为什么使用 pulseaudio 禁用扬声器会影响 USB 耳机的麦克风检测，但这种情况似乎确实如此。
我仍然很好奇如何从 alsa 或 pulseaudio 执行此操作，同时保持驱动程序完好无损。
