Ubuntu 22.04.4蓝牙功能异常：耳机连接后无声音及后续连接问题求助

大家好，我是Ubuntu的新用户，最近碰到了蓝牙耳机的棘手问题，想请各位大佬帮忙支支招！

我已经尝试了不少排查操作：重启系统、检查蓝牙服务状态、卸载后重新安装蓝牙驱动，但不管怎么折腾，最好的情况也只是耳机能显示连接成功，可声音还是从笔记本扬声器里出来，耳机完全没声。

下面是我最初检查蓝牙服务状态的输出：

● bluetooth.service - Bluetooth service

有没有朋友能帮我解决这个问题？万分感谢！

更新：按Daniel建议操作后的反馈 #

嗨Daniel，谢谢你的回复！按照你的方法操作后，一个明显的改善是：现在检查蓝牙状态时，之前那些UUID相关的错误消失了。下面是新的服务状态输出：
