无法同步我的蓝牙耳机和我的笔记本电脑

Question

我收到了这个错误

Connection Failed: blueman.bluez.errors.DBusFailedError: Protocol not available

我尝试了几种解决方案，比如重新安装blueman。

和脉冲音频无法加载蓝牙模块15.10/16.04/16.10

但没什么对我有用的。下面是已安装的东西的列表

Answer 1

这文章中的解决方案对我有用：

1. 确保此包已安装sudo apt-get安装脉冲音频模块-蓝牙
2. 运行命令pactl加载模块模块-蓝牙发现

然后从蓝牙设备中删除该设备，并再次对其进行配对。

如果它有效，可以考虑将第二个命令添加到启动设置中，这样就不必在每次重新启动之后再次运行它。
