我已经搜索了好几天，想知道为什么我的蓝牙耳机无法使用。但还是没能找到正确的答案。
我在配备 Qualcomm Atheros QCNFA765 芯片组的全新联想 T14 Gen 4 AMD 笔记本电脑上运行 Ubuntu 22.04 并安装所有最新更新。到目前为止，我连接任何其他蓝牙设备（例如鼠标或手机）都没有遇到问题。
从头开始。全新安装后，当我连接耳机时，即使选择耳机作为声音接收器，我也听不到任何声音。一段时间后，耳机与系统断开连接。无论我使用的是哪种配置文件（A2DC 或 HSF），都无所谓。
有时当我尝试手动连接耳机时，会收到连接失败的错误。蓝牙控制输出也没有信息。
系统日志的输出：

我尝试用 Google 搜索所有这些问题。但没有找到解决方案。
根据论坛上的建议，我已将系统升级为 pipewire 设置。问题仍然存在。
输出wpctl 状态命令：

我认为 Bluez 可能不是最新的。根据来自这里，我编译了最新版本5.70。但这也没有解决问题。

我开始想，这可能是硬件相关的问题。你怎么看？目前，我没有机会使用基于 Windows 的操作系统来验证我的计算机硬件。我订购了一个外部 USB 蓝牙适配器，它将在周末后到达。让我们拭目以待。
先感谢您。
