我刚买了一个新耳机，HyperX Cloud Alpha S。当我使用插孔连接器连接耳机时，麦克风和扬声器都可以工作，但是当我使用 USB 连接耳机时，只有扬声器可以工作，并且麦克风甚至没有列在要选择的输入设备中。
alsamixer显示结果如下：
我的alsa-base.conf内容如下：

我的编解码器：
❯ cat /proc/asound/card*/codec* | grep Codec
Codec: Realtek ALC298
Codec: Nvidia GPU 60 HDMI/DP
其中pavucontrol麦克风显示为unplugged：
我尝试了hdajackretask但不知道该怎么做，但是每当我尝试“立即申请”时它都会失败并显示错误消息。
杀死 pulseaudio 也不起作用。
同一副耳机可以在运行 Windows 的其他机器上使用，甚至在我的计算机上双启动 Windows 也可以使用。
我不明白为什么它不能识别麦克风，或者为什么在 ubuntu 中插入麦克风并使其工作会如此困难。！！！
有人能帮我让 Ubuntu 检测到这个麦克风吗？我试过 Ubuntu 19.10 Pop!_OS，还有 Ubuntu 20.04。同样的问题。
我插入耳机时的系统日志如下：

答案1
内核中有一个错误。一个月前已经修复了。所以我怀疑它是否会应用于 ubuntu 内核。请参阅https://lkml.org/lkml/2020/4/4/197
