我目前在配对雅马哈 YAS-103音响与我的系统配对。它会出现在我的蓝牙管理器屏幕中，但我似乎无法将其配对。使用0000密钥失败，默认配对按钮也失败。
正在使用的蓝牙适配器正在使用Iogear GBU521W6之所以选择它，是因为另一个线程将其列为可以与 Ubuntu 一起使用。查询lsusb结果如下：
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 003: ID 046d:c52b Logitech, Inc. Unifying Receiver

答案1
检查pactl list short它module-bluetooth-discover是否是蓝牙 A2DP 声音所必需的。已知某些版本的 Blueman 会在启动过程中将其删除。
您可以module-bluetooth-discover加载
sudo pactl load-module module-bluetooth-discover
然后与设备配对，A2DP 即可工作
如果你想要或需要 HSP/HFP，那么你需要固件
