答案1
理论上，你应该直接访问settings并：
Output在您的蓝牙设备中选择Configuration在个人资料中选择HSP，而不是A2DP- 现在
Input您将看到您的蓝牙设备！
但这在 20.04 中似乎不起作用。
=> 因此请按照https://atish3604.medium.com/solved-bluetooth-headset-mic-not-working-detected-in-ubuntu-20-04-86a5236444d0（也显示在在 Ubuntu 18.04 中使用带麦克风的蓝牙耳机（HFP）但截至 2023 年 8 月有一个错误）。
现在，您可以选择
Handsfree：质量较低，但输入/输出Headset：高质量但仅输出
