升级到 Ubuntu 20.10 后，我的 HyperX Cloud II 上的麦克风停止工作了。有人知道如何解决这个问题吗？我已经尝试了很多不同的方法，但都没有用。
我将在上面列出一些可能有用的输出：

这款耳机使用 USB 插入我的电脑，耳机上的音频正常，只是麦克风完全不工作。我已经检查过它是否处于静音状态，我也尝试了内核 5.9.3。但什么都不起作用。如果有人知道如何解决这个问题，我真的很感激。

我的 HyperX Cloud 耳机也遇到了同样的问题。在我安装 pavucontrol 后，这个问题（神奇地）解决了（https://wiki.ubuntuusers.de/pavucontrol/），并用它来配置我的声音设置。
