想把一些无线耳机连接到我的笔记本电脑上。他们几天前就工作了,然后停了下来,我不知道为什么。在此之前,它可以工作几天,然后停止,直到我重新启动或只是尝试了几个小时后。现在它已经两周没起作用了。

看起来OP在这个问题的评论中找到了一个解决方案,但是对于其他人来说,对我来说,修复它只需要一个systemctl --user enable pulseaudio
和systemctl --user start pulseaudio
。

许多消息来源建议在/etc/蓝牙/main.conf中设置ControllerMode = bredr
和AutoEnable = true
,这在以前的安装中为我提供了帮助。
然而,在这种情况下,我不得不注释掉行ControllerMode = bredr
,以解决“br-connection-profile-不可用”错误。
(这两件事都发生在拱门上,不知道是什么造成了这一变化)

我评论了AutoEnable = true
=> #AutoEnable = true
