音频输入不起作用，无论是内部还是外部

我不明白为什么我的 HP Omen 15 ek0006nl 上的音频输入无法正常工作。在设置/声音/输入我只找到后置麦克风 - 内置音频音量条停留在固定水平，如果我尝试录制某些内容或拨打电话，我会收到白噪音。

如果我使用蓝牙耳机（索尼 WH-1000XM3），也会发生类似的情况：相关的音频输入设备被识别，但设置中的音量条停留在零，我没有得到任何反馈。如果我使用外部 USB 声卡 (UGREEN FBA_30143)，也会发生同样的情况。

在之前的所有案例中，输出音频完美运行，带扬声器、蓝牙、3.5mm插孔和外置USB声卡。

这是可能有用的东西。

我运行 Debian 10 bullseye 5.10.0-7-amd64 与 Windows 10 双启动，音频输入运行良好。
