带麦克风的蓝牙耳机 Jabra Elite 85t 通常运行良好，但有时过一段时间就会变得混乱，我不得不将它们放回盒子里，甚至重新启动系统。
我正在使用新安装的 Ubuntu 22.10 - 默认是 Pipewire / Wireplumber。
当我将 Jabra 从盒子中取出时，它们会自动连接到蓝牙 - 从journalctl -f

这里有两个潜在问题。第一个设备被标记为键盘...
(II) event24 - Jabra Elite 85t (AVRCP): is tagged by udev as: Keyboard
最后一行显示为红色，表示错误：

如果我跑步systemctl status bluetooth.service我会得到：

我的 Ubuntu 22.10 系统没有安装这三个 dep。
最后这是声音控制面板：
