我遇到了一个大问题，昨天 skype 可以正常工作，但今天却无法正常工作。当我进行 skype 测试通话时，我听不到任何声音，而当我与另一个人通话时，他们会听到我的音乐和他们自己的声音两次。因此我的输入被忽略，我的输出被视为我的声音输入。我该怎么做才能解决这个问题？
我有 PulseAudio 作为音频服务。
另外，当我启动机器并进入声音设置时，它看不到我已插入麦克风，我必须将其移除并重新插入，然后通过切换按钮激活它。
pulseaudio --dump-conf

经过长时间的聊天讨论后，我最终提出了一个古老的小技巧。
创建新用户。如果它有效，那么说明您的主目录中的隐藏偏好设置妨碍了您，只需移动它们mkdir ~/conf.backup && mv ~/.* ~/conf.backup/并重新启动会话就可以了。
一种破坏性较小的方法可能是删除~/.config/pulse：
rm -R ~/.config/pulse
这仅删除与脉冲相关的配置。
