蓝牙耳机经常断开连接

我正在尝试将 Sony WH-CH510 连接到 Ubuntu 22.04。配对正常，但连接始终无法解决 - 我收到“已连接”消息，但一分钟后它再次断开连接，并且耳机从未出现在 pulseaudio 输出中。

错误信息各不相同，包括

bluetoothd src/device.c:search_cb() error updating services: Input/output error

unexpected start frame

ServicesResolved: no

尤其令人费解的是，在另一台运行 Ubuntu 22.04 的计算机上一切都运行正常。

这是一些信息。请告诉我还有什么有用的信息。

这可能是某种硬件冲突吗？

剑桥硅基无线电不可靠吗？
