我在一台配备 Intel Wi-Fi 6E AX210 无线网卡的框架笔记本电脑上运行 ubuntu 21.04。我iwlwifi-ty-59.601f3a66.0.tgz从这里并将其放入/lib/firmware，因此应该是最新的。此外，我的所有软件包都是最新的。
我想通过蓝牙耳机而不是笔记本电脑的内置扬声器收听音频。但是，无论pavucontrol我做什么，它似乎都没有显示出来，尽管耳机已成功配对。更多详细信息如下。
我的蓝牙设备配对成功：

但是，我无法让它显示在pavucontrol：
$ pacmd list-sinks
1 sink(s) available.
* index: 0
name: <alsa_output.pci-0000_00_1f.3.analog-stereo>
我有模块蓝牙发现并尝试过：
$ pactl unload-module module-bluetooth-discover
$ pactl load-module module-bluetooth-discover
25
以下是 list-modules 的输出：
$ pacmd list-modules | grep -i bluetooth -B 1 -A 5

以下是我在 dmesg 中找到的内容：
