我在相当新的 Dell XPS 13 上安装了 Kubuntu 20.04。当我启动计算机时，默认情况下，我在 Kubuntu 音频设置中看到 2 个麦克风。（此时没有连接耳机，我也在输出设备中确认了这一点！）
- 内置麦克风
- 头戴式麦克风
在 pavucontrol 下，在“输入设备”选项卡中，端口具有以下功能
- 内置麦克风（已插入）
- 头戴式麦克风（已插入）
- 麦克风（未插电）
一旦我连接耳机（耳机 + 麦克风组合插孔），pavucontrol 中的麦克风条目就会从（拔掉插头）到（插入）并成为选定的值。发生这种情况时，我听不到任何声音，即使输出设备是耳机。我必须将输入设备更改为耳机麦克风或内置麦克风。
但是，在所有这些组合中，麦克风只有在设置为内置麦克风时才有效。在这种情况下，使用笔记本电脑麦克风。
我已经确认我的耳机没有问题。

我确实希望有人能帮助解决这个问题，耳机麦克风不工作真是很烦人，因为除非我将自己静音，否则我无法在通话时打字，这在会议期间不是最实用的！
谢谢
