蓝牙耳机失去连接

蓝牙耳机失去连接

我有一个新的 Corsair HS70 蓝牙耳机,配有 USB 适配器,用于 Zoom 会议。但连接不可靠。

经过几次连接尝试后,设备成功连接。但是,重启系统后,无法再建立连接。配对已存在,耳机被标记为受信任。

短时间内,连接正常,我听到耳机里有相应的声音。然而,1-2 秒后,连接再次中断。耳机里听到断开连接的声音,并bluetoothctl可以看到输出:

[bluetooth]# connect 20:06:10:12:D4:45 
Attempting to connect to 20:06:10:12:D4:45
[CHG] Device 20:06:10:12:D4:45 Connected: yes
Failed to connect: org.bluez.Error.Failed
[CHG] Device 20:06:10:12:D4:45 Connected: no

有人知道如何解决这个问题吗?

我仍然遇到很多有关蓝牙的问题,但以下尝试可能会对您有所帮助。

这是我个人使用过并且工作过一段时间的东西。

第一步:检查 pulse-audio 及其依赖项是否已安装: sudo apt install pulseaudio pulseaudio-utils pavucontrol pulseaudio-module-bluetooth

第二步:当我们验证它时,我们需要创建或编辑这个音频配置文件:sudo gedit /etc/bluetooth/audio.conf 包括下几行:#This section contains general options [General] Enable=Source,Sink,Media,Socket

第三:现在是时候保存文件并重新启动蓝牙服务了。 sudo service bluetooth restart
