我正在使用 KDE Plasma 运行 Arch Linux。当我尝试通过 KDE Plasma GUI 连接到无线蓝牙扬声器时，失败。
这是我在屏幕截图中逐步完成的步骤。我单击“添加设备”，然后单击显示“PIN”匹配的按钮。请注意，由于它是蓝牙扬声器，因此没有 PIN 码。因此，无论我单击“PIN 匹配”还是其他选项，下一个屏幕都会显示设置失败。
当我启动到 Windows 10 时，它可以连接到扬声器。我的智能手机也连接到扬声器。
这是 的输出systemsettings5。当我尝试连接到扬声器时，我首先单击 PIN 匹配，然后单击显示不匹配的按钮。

答案1
KDE 的蓝牙管理器bluedevil似乎由于以下错误而失败：
[...] kf.bluezqt: PendingCall Error: Authentication Failed"
您可以尝试列出的其他一些 GUI这里， 例如blueman。 （您可以使用包管理器安装它们。）gnome-control-center如果您不使用 GNOME，请不要安装。
如果它们不起作用，请尝试以下操作：
- 在控制台运行
sudo pacman -S pulseaudio-alsa pulseaudio-bluetooth bluez-utils bluez - 然后跑
bluetoothctl并跟随这些说明来自 Arch Wiki（您可能不需要“媒体控件”下的部分）。 - 如果仍然不起作用，请
systemsettings5在控制台中运行并通过日志询问。
