还有一个关于连接蓝牙耳机的问题

Question

我的蓝牙耳机（索尼 WF-1000XM3）无法正确连接（Ubuntu 22.04.1 LTS，在以前的版本上也无法使用）。我一直在尝试这个网站上类似问题提出的各种解决方案，其中之一确实有效。有一次。我不知道当时我可能会做些不同的事情，但我注意到行为上的差异可能会告诉你一些事情：通常，当连接到耳机时（只有通过断开连接并重新设置才能起作用），蓝牙设置中的“连接”滑块会变灰。耳机无法识别此连接，并且它们不能用作声音输出设备。它们通常会立即断开连接。

上面链接的脚本起作用了一次，“连接”开关也起作用了。

通过配对bluetoothctl可得到以下输出：
