无法连接蓝牙耳机

我有 Sennheiser pxc550-ii 蓝牙耳机，我想将其与我的 Ubuntu 20.04 桌面配对，并让 aptx-hd 和 aptx-ll 编解码器正常工作。值得注意的是，我已经安装了后者这ppa。还值得注意的是，我可以使用 bt 与我的 bt 扬声器完美配对。

我尝试使用默认的 bloothtooth 工具以及 blueman-manager。在这两个工具中，我都可以在可用蓝牙设备列表中看到耳机，但都无法配对。

然后我转向关注这指南，他们建议的命令的输出是：

第一个命令：

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

第二条命令：

第三条命令：

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

我也注意到了这个错误信息：

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

当我尝试配对/连接时，可以找到终端输出这里该文件中最引人注目的一行是：

> 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)

不过我的耳机确实开机了。有人能建议我该如何解决这个问题吗？

答案1

我发现这很好用为什么我会收到“连接 PulseAudio 失败”错误？.看一眼吧（：

快速注释：

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

  2. sudo nano /etc/pulse/client.conf [将变量 autospawn = now/yes 更改为 autospawn = no]

  3. 重启

  4. 帕武控制

现在您可以选择可用的蓝牙设备进行声音输出
