Arch Linux / KDE Plasma 上的藍牙揚聲器未連接

  • November 25, 2021

我正在使用 KDE Plasma 執行 Arch Linux。當我嘗試通過 KDE Plasma GUI 連接到無線藍牙揚聲器時，它失敗了。

這是我在螢幕截圖中的分步操作。我點擊“添加設備”，然後點擊顯示“PIN”匹配的按鈕。請注意，由於它是藍牙揚聲器，因此沒有 PIN 碼。因此，無論我點擊“PIN 匹配”還是其他選項，下一個螢幕都會顯示設置失敗。

當我啟動到 Windows 10 時，它可以連接到揚聲器。我的智能手機也連接到揚聲器。

這是 的輸出systemsettings5。當我嘗試連接到揚聲器時，我首先點擊 PIN 匹配，然後點擊顯示不匹配的按鈕。

由於這個錯誤， KDE 的藍牙管理器bluedevil似乎失敗了：

[...] kf.bluezqt: PendingCall Error: Authentication Failed"

您可以嘗試此處列出的其他一些 GUI ，例如blueman. （您可以使用包管理器安裝它們。）gnome-control-center如果您不使用 GNOME，請不要安裝。

如果它們不起作用，請嘗試以下操作：

  • 在控制台執行
sudo pacman -S pulseaudio-alsa pulseaudio-bluetooth bluez-utils bluez
  • 然後執行bluetoothctl並遵循Arch Wiki 中的這些說明（您可能不需要“媒體控制項”下的部分）。
  • 如果它仍然不起作用systemsettings5，請在控制台中執行並使用日誌詢問它。
