为什么我的蓝牙耳机从“声音设置”中消失了以及如何恢复它?

为什么我的蓝牙耳机从“声音设置”中消失了以及如何恢复它?

有点类似于我在 Ubuntu 中配对了我的蓝牙耳机 (Turtle Beach Ear Force PX5),配对后它首先出现在“声音设置”中。它最初不起作用,所以我开始调整一些设置。我调整了麦克风上的设置,突然间输出/输入设备都消失了。该设备适用于 Windows,但为了使其同时与我的手机配合使用(耳机是 2ch),我通常会禁用麦克风,只在需要时启用它。

我捕获了来自 bluetoothd 的调试输出:

我尝试删除并修复该设备,但似乎我意外地在深处设置了一些持久的设备设置,并且该设备不再显示在“声音设置”中,无法让我更改它。有人能指点一下吗?我正在运行 Ubuntu 12.04。

在这里找到了我的答案:

使用 A2DP 通过蓝牙播放音频时消除 0.5 秒的延迟

blt@aurora:/$ pactl list cards short
0   alsa_card.pci-0000_01_00.1  module-alsa-card.c
1   alsa_card.usb-Generic_Turtle_Beach_USB_Headset_0000000001-00-Headset    module-alsa-card.c
2   alsa_card.pci-0000_00_14.2  module-alsa-card.c
8   bluez_card.C8_84_47_04_21_6F    module-bluetooth-device.c

blt@aurora:/$ pactl set-card-profile bluez_card.C8_84_47_04_21_6F a2dp

并且再次运行

答案2

我遇到了同样的问题,当我调整声音设置时,我的蓝牙耳机突然从输出列表中消失了。

我关注了 Brett 的回答中的链接,并部分关注了 Roelf 的回答:

  1. 安装 pavucontrol:sudo apt install pavucontrol
  2. pavucontrol从菜单运行
  3. 转到“配置”
  4. 我的蓝牙耳机也有麦克风,所以我将配置文件设置更改为“输出 + 模拟单声道输入”

我改变此项后,耳机和麦克风重新出现在声音设置中。
