![蓝牙耳机无法与 Ubuntu 18.04 配合使用](https://linux22.com/image/1069410/%E8%93%9D%E7%89%99%E8%80%B3%E6%9C%BA%E6%97%A0%E6%B3%95%E4%B8%8E%20Ubuntu%2018.04%20%E9%85%8D%E5%90%88%E4%BD%BF%E7%94%A8.png)
我有一些蓝牙 5.0 耳机。它们可以很好地与我的 Android 手机配合使用,但当我将它们连接到我的 Ubuntu 18.04 笔记本电脑 (HP Spectre x360) 时,它们连接了一两秒钟,但随后声音有点冻结,并发出奇怪的声音,就像有什么东西撞坏了一样。
只是希望有人知道可以尝试什么。

答案1
我在 Ubuntu 20.04 上遇到了和你描述的完全相同的问题。试试这个:
编辑蓝牙配置文件:
sudo nano /etc/bluetooth/main.conf
代替:
#ControllerMode = dual
和:
ControllerMode = bredr
重启蓝牙:
sudo service bluetooth restart
尝试再次连接您的耳机。
