無法連接藍牙耳機

我有 Sennheiser pxc550-ii 藍牙耳機，我想將其與 Ubuntu 20.04 桌面配對，並且 aptx-hd 和 aptx-ll 編解碼器可以正常工作。值得注意的是我安裝的後者這帕帕。還值得注意的是，我可以使用 bt 與我的 bt 揚聲器配對。

我嘗試過使用預設的bloothtooth 工具以及blueman-manager。在這兩個裝置中，我都可以在可用藍牙裝置清單中看到耳機，但兩者都無法配對。

然後我轉向關注這指南，他們建議的命令的輸出是：

第一個命令：

jam@jam-ncase:~$ lsmod | grep bluetooth
bluetooth             454656  49 btrtl,btintel,btbcm,bnep,btusb,rfcomm
ecdh_generic           16384  2 bluetooth
rfkill                 28672  11 asus_wmi,bluetooth,cfg80211
crc16                  16384  2 bluetooth,ext4

第二條指令：

jam@jam-ncase:~$ dmesg | grep Bluetooth

第三條命令：

第四：

jam@jam-ncase:~$ rfkill list
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

我也注意到了這個錯誤訊息：

jam@jam-ncase:~$ pactl load-module module-bluetooth-discover
Failure: Module initialisation failed

可以找到我嘗試配對/連接時的終端輸出這裡該文件中最突出的一行是：

> HCI Event: Disconnect Complete (0x05) plen 4             #56 [hci0] 25.099314
        Status: Success (0x00)
        Handle: 256
        Reason: Remote Device Terminated due to Power Off (0x15)

不過我的耳機肯定是開機的。有人可以建議我應該如何嘗試解決這個問題嗎？

答案1

我發現這工作得很好為什麼我會收到「連線 PulseAudio 失敗」錯誤？.看一下它一次（：

快速註釋：

  1. sudo apt-get --purge --reinstall 安裝pulseaudio

  2. sudo nano /etc/pulse/client.conf [將變數 autospawn = now/yes 改為 autospawn = no]

  3. 重啟

  4. 帕武控制

現在您可以選擇可用的藍牙裝置進行聲音輸出
