我正在使用带麦克风的飞利浦 UT102 蓝牙耳机。Mint 无法通过蓝牙检测到其输入源麦克风，但只有耳机可以工作。我想知道这是否是我从亚马逊购买的损坏部件，但事实并非如此。

我懂了耳机输入可用：否来自pacmd info。另外，不更改为热解蛋白/氢解蛋白配置文件。为什么只在 Linux 上如此？

上述错误是否意味着 Linux 系统不允许耳机切换到 HSP/HFP 配置文件或其他一些错误？
为了进一步测试，我在同一台机器上安装了 Windows 10，并且蓝牙麦克风在输入配置文件中运行良好。
使用 Zoom 测试聊天进行了测试，并且两者均正常运行：
有人知道解决这个问题的方法吗？或者唯一的解决办法是购买一个带有适用于 Linux 的麦克风的新蓝牙耳机？:)
