答案1

打开一个终端。

剪切并粘贴以下命令（全部一起）并按回车键：

pactl unload-module module-bluetooth-discover
pactl load-module module-bluetooth-discover
sudo systemctl restart bluetooth

系统将提示您输入密码。输入密码。退出终端。

应该可以再次启动并运行。我认为这是蓝牙的一些错误。

但是，每次重新启动时，您都必须在终端中运行该程序。

我只是把它放在桌面上的便签上，每次登录后运行它。

答案2

感谢 Pilot6，此蓝牙设备的驱动程序：

总线 003 设备 004：ID 04ca：3011 Lite-On Technology Corp.

现在位于 Yakkety 提议的内核中，当验证任务完成后，它将在 Yakkety 更新中可用。

在此之前，您可以先在 Yakkety 上启用建议的更新来尝试一下。
