我正在尝试将 Skullcandy Crusher Wireless 耳机与电脑配对。我能够成功配对并在声音菜单中选择它们，但不知为何音频仍然通过内置扬声器播放？
我尝试了477933， 和https://www.nielsvandermolen.com/bluetooth-headphones-ubuntu/无济于事
我的设置菜单如下所示：
这很奇怪，因为它看起来好像输出和输入都连接在一起，但我从来没有这样设置过它们？
有人知道如何解决这个问题吗？

当我进入时，alsamixer它显示我的耳机已静音，因此我取消了静音，正如上面的 SO 问题所示，但这也无济于事。
更新
好的，我正在处理声音故障排除指南并发现了几件值得注意的事情。
- 当我执行时
pacmd
>>> list-sinks
>>> exit
它将蓝牙耳机列为接收器，但退出时，我的蓝牙系统崩溃了，我必须重新启动耳机才能重新连接。以下是该命令的输出：

注意耳机没有静音，输出音量为100%
当我执行时，
aplay /usr/share/sounds/alsa/Front_Center.wav声音从耳机里出来！但如果我返回设置菜单并尝试使用test扬声器，或者如果我通过 Firefox 播放音乐，声音仍然会从内置扬声器中出来。其余步骤均正常，但我注意到，当我使用
aplay -l列表时，不包括耳机作为音频接收器，这可能很重要？我不知道。
以下是本指南相应命令的输出：

答案1
我首先建议重建新的脉冲音频您的用户帐户的配置。在许多情况下，这可能会解决问题，或者至少排除与 pulseaudio 配置相关的问题。
软件包升级后，旧pulseaudio配置文件有时会与新版本发生冲突pulseaudio。要解决此问题，请按照以下步骤操作：
通过在终端中运行以下命令将
~/.config/pulse/配置目录备份到：~/.config/pulse_old/mv ~/.config/pulse/ ~/.config/pulse_old/之后，请重新启动系统以建立新的
pulseaudio配置文件。~/.config/pulse/将自动创建一个新目录。现在测试您的音频。
如果，不知何故，应用此修复后如果您决定返回到应用修复之前的状态，请按照以下步骤操作：
在终端中运行以下命令：
rm -r ~/.config/pulse/在终端中运行以下命令：
mv ~/.config/pulse_old/ ~/.config/pulse/重新启动系统。
然而，如果一切顺利，问题得到解决~/.config/pulse_old/，您可以通过在终端中运行以下命令来删除备份的旧配置目录以释放空间（如果您愿意）：
rm -r ~/.config/pulse_old/
答案2
我曾经遇到过类似的问题，视窗和Linux，这两个系统的解决方案都是禁用耳机麦克风（选择内置麦克风）。
它似乎（此处讨论）蓝牙接口仅支持其中一种
- 高品质 (a2dp) 音频输出，或
- 高品质 (a2dp) 麦克风输入，或
- 低质量（hsp/hfp）输入和输出。
可能是您的耳机麦克风正在以高质量捕捉声音，因此它会阻塞您的耳机扬声器。
答案3
如果你使用的是 Ubuntu 20.04，我建议代替 PulseaudioPipewire它将适用于您的所有应用程序，因为它旨在通过为 JACK 客户端提供与 PulseAudio 兼容的服务器实现和与 ABI 兼容的库来取代 PulseAudio 和 JACK 。
我运行的是 Ubuntu 20.04.3，到目前为止，Pipewire 运行非常稳定。我的蓝牙耳机现在可以与 Microsoft Teams 配合使用。就我而言，我同时运行 Bitwig、Spotify、Youtube 等，它可以与每个输出设备（蓝牙耳机、RME 音频接口、内置扬声器）配合使用。
我发布了安装步骤的链接，对我有用：在 Ubuntu 20.04 中用 Pipewire 替换 Pulseaudio
