蓝牙在华硕 ROG M8F Ubuntu 22.04.3LTS 上无法工作

这个问题已被问过多次，但没有发布答案。

无法在 Ubuntu 23.10（华硕 ROG ROG Flow X13 GV302XV）上打开蓝牙似乎是一个很好的答案，但在我的情况下不起作用。

sudo dkms install btusb/4.1

在构建结束时失败。然而，这个答案是针对 USB BT 连接的问题。就我而言，蓝牙是在主板上实现的。

$ sudo service bluetooth status

表明服务运行正常。但是....右上角状态栏中没有蓝牙图标（因为它在我的使用BT适配器的M8H机器上）

蓝牙以前可以在这台机器上运行，但在安装早期版本的 Ubuntu 时可能会出现这种情况。

主板规格为 bt v4.0/3.0+HS，采用 Intel Z170 芯片组。

问题：在 Ubuntu 的 BT 设置中，蓝牙已打开，设备搜索轮正在旋转，但没有找到任何设备。即使我安装了 BT 适配器也是如此。旁边的台式机是华硕 ROG M8H 主板，没有集成 BT。安装加密狗后，它会立即连接到选定的 BT 设备。两台机器都运行相同版本的 Ubuntu。

华硕有 bt 固件，但只有 Microsoft 格式。他们很清楚他们不支持*NIX，但显然我们很多人在 ROG 机器上运行 Ubuntu 都没有问题。

我希望能够通过 BT 在每台桌面上仅运行一个扬声器，而不是使用四个扬声器组，每个扬声器组硬连线到每台计算机。是的，我知道我一次只能将该设备与一台电脑配对。

sudo dmesg|grep Blue

bluetoothctl启动了，但我对该工具的了解还不够，无法有效地使用它。看起来工作正常。只是没有发现任何设备（是的，wifi 天线已连接。手册有点暗示 BT 需要它）

正如机载 BT 功能所预期的那样
