直到昨天，蓝牙在 Ubuntu 22.04.4 中工作正常，但现在不行了

我通过重启、检查蓝牙状态、移除并重新安装蓝牙等方式进行了一些故障排除。但无论我做了什么，我能做的最好的事情就是我的耳机连接上了，但声音来自笔记本电脑扬声器，而不是耳机。

这是当前状态。有人能帮我解决这个问题吗？我是 Ubuntu 的新用户。 谢谢

嗨 Daniel，谢谢你回答这个问题。按照你的回答后，有一件事是正确的，那就是我在状态检查中没有收到任何错误

这是完整的日志，journalctl -r -b -0 -u bluetooth 你可以看看

再次感谢。

这是造成蓝牙已被禁用。请先检查是否有任何硬件开关。然后运行以下命令来启用它：

rfkill unblock all
reboot

如果仍然看到错误，我们可以重新安装 BlueZ：

sudo rm -rf /var/lib/bluetooth /etc/bluetooth
apt download bluez
sudo dpkg -P --force-all bluez
sudo dpkg -i ./bluez*.deb

这应该会重新安装 BlueZ。如果 BlueZ 仍然损坏，请将标志添加-d到ExecStart中的行/lib/systemd/system/bluetooth.service，重新启动，并附加 的完整日志journalctl -r -b -0 -u bluetooth。
