蓝牙服务“变灰”且无响应

Question

这不是一个答案，但我有大量的数据可供人们最终研究这个问题，并且它们不适合发表评论。

我遇到了类似的问题 - Kinetic 22.10 全新安装，默认使用 pipewire/wireplumber。

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。

这是当我将 Jabra 从盒子中取出时在新启动的系统上发生的情况 - 它们在配对后会自动连接到蓝牙 - 来自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：

bluetoothd[1129]: src/service.c:btd_service_connect() a2dp-sink profile connect failed for 30:50:75:BE:B0:3D: Device or resource busy

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