我这里有一个相当奇怪的声音问题。我刚买了一个“Teufel Cinebar One”，它集成了一个 USB 声卡。它与运行 Windows 10 的商务笔记本电脑配合得很好。
现在在带有 Unity 桌面的 Ubuntu 20.04 中，唯一有效的是“设置/声音”中的“测试声音”功能。但前提是没有其他声源（即 Google Chrome 中的 youtube 或 vlc），并且 pavucontrol 未运行。
有人有想法吗？
我将附上一些来自 pulseaudio 的信息。

答案1
我自己发现了。“Teufel Cinebar One”USB 声音似乎仅支持 48000Hz 输出。因此，编辑 /etc/pulse/daemon.conf，并将行
; default-sample-rate = 44100
到
default-sample-rate = 48000
然后重新启动 pulseaudio：
pulseaudio -k
这招真是太管用了 :)
