Ubuntu 18.04.3 蓝牙连接失败：org.bluez.Error.Failed (INTEL® DUAL BAND WIRELESS-AC 9560 + BLUETOOTH)

Question

我无法连接我的蓝牙耳机 Sony MDR-XB950N1。以下是一些可能有帮助的信息：

1. 这是一个从头开始的 Ubuntu 18.04.3（我第一次做了一些更改，所以这次是完整的）

2. 输出： rfkill list

       Hard blocked: no
   1: phy0: Wireless LAN
       Soft blocked: no

3. 输出： dmesg | grep Blue

5. 尝试bluetoothctl：

6. 我的蓝牙罗技 M585 工作正常：

   Device E1:B5:43:77:D0:97 M585/M590
   

7. tail -f /var/log/syslog尝试再次连接时的输出bluetoothctl：

   Jan  4 16:46:43 bonavel bluetoothd[887]: 04:5D:4B:96:D5:65: error updating services: Host is down (112)
   

8. 输出 pactl list | grep -i bluetooth

   Name: module-bluetooth-policy
       module.description = "Policy module to make using bluetooth devices out-of-the-box easier"
   Name: module-bluetooth-discover
       module.description = "Detect available Bluetooth daemon and load the corresponding discovery module"
       module.description = "Detect available BlueZ 5 Bluetooth audio devices and load BlueZ 5 Bluetooth audio drivers"
   

9. 应用此解决方案，它仍然无法正常工作。

10. 应用此解决方案，现在我能够配对和连接，但尽管它很快断开连接，但它无法再现声音。

11. 第bluetoothctl10 项之后的输出。

12. 我按照此说明在工厂恢复了耳机。然后我能够配对并连接到它。但是当我通过它放一些音频时，感觉有很多干扰，只有一些随机的非常切割的噪音，我什至无法与正在播放的内容相关联。然后我能够断开连接并再次连接，但现在根本没有播放声音。然后大约 1 分钟后，耳机失去了连接。

13. 在软件更新设置中，如下所示：

我已经搜索了 2 个多小时并应用了我找到的所有可能的解决方案，但没有一个解决了我的问题，所以我从头开始重新安装了 Ubuntu 18.04.3。

Answer 1

问题是其中一根天线Intel Corporation Wireless-AC 9560已断开。我打开电脑，连接天线，蓝牙工作正常，Wifi 信号更好。
