Ubuntu 22.10連接藍牙耳機報錯br-connection-profile-unavailable解決方法

今天新版Ubuntu 22.10發佈,高高興興升級完成後,發現:1.Flameshot異常;2.沒法連接AirPods Pro2 耳機了;3.定製ibus的gnome 插件不兼容(預料之中)。

藍牙耳機連不上的的時候,症狀爲 Failed to connect: org.bluez.Error.Failed br-connection-profile-unavailable

[bluetooth]# connect C0:95:6D:C0:A3:92

這就是linux用戶的日常,搜索後確定大致原因爲,Ubuntu 22.10桌面版本音頻服務從PulseAudio切換到PipeWire, 導致的服務異常。

解決方法

    1. 安裝依賴包

      sudo apt install wireplumber libspa-0.2-bluetooth wireplumber-doc

    依賴包解釋說明

    • WirePlumber is a modular session / policy manager for PipeWire
    • libspa-0.2-bluetooth: libraries for the PipeWire multimedia server - bluetooth plugins
    1. 重啓 wireplumber

      systemctl --user restart wireplumber

    1. 重新連接AirPods耳機, 看最後返回successful

      ➜ work bluetoothctl Agent registered [bluetooth]# connect C0:95:6D:C0:A3:92 Attempting to connect to C0:95:6D:C0:A3:92 [CHG] Device C0:95:6D:C0:A3:92 Connected: yes [NEW] Endpoint /org/bluez/hci0/dev_C0_95_6D_C0_A3_92/sep1 [NEW] Endpoint /org/bluez/hci0/dev_C0_95_6D_C0_A3_92/sep2 [NEW] Endpoint /org/bluez/hci0/dev_C0_95_6D_C0_A3_92/sep3 [NEW] Transport /org/bluez/hci0/dev_C0_95_6D_C0_A3_92/sep1/fd0 [CHG] Transport /org/bluez/hci0/dev_C0_95_6D_C0_A3_92/sep1/fd0 Delay: 0x05dc (1500) Connection successful
