答案1
运行以下命令：
sudo apt-get install pulseaudio-module-bluetooth
pactl load-module module-bluetooth-discover
然后尝试从蓝牙设备中删除/移除该设备并再次配对。
我试过了，它有效
答案2
就我而言，这些命令帮助了我
sudo apt-get install pulseaudio-module-bluetooth
sudo killall pulseaudio
pulseaudio --start
sudo systemctl restart bluetooth
答案3
在另一个论坛中找到了为我解决问题的这个帖子：蓝牙 a2dp 不工作（包括连接日志）
答案4
这是我在 Ubuntu 20.04 中蓝牙出现问题时用来“修复蓝牙”的‘魔术技巧’。
sudo rmmod btusb
sudo modprobe btusb
我将其保存在一个方便的~/bin/fix-bluetooth.shshell 脚本中。
没有其他方法可行，但对我来说，这个每次都有效。
