![音频输入不起作用,无论是内部还是外部](https://linux22.com/image/15388/%E9%9F%B3%E9%A2%91%E8%BE%93%E5%85%A5%E4%B8%8D%E8%B5%B7%E4%BD%9C%E7%94%A8%EF%BC%8C%E6%97%A0%E8%AE%BA%E6%98%AF%E5%86%85%E9%83%A8%E8%BF%98%E6%98%AF%E5%A4%96%E9%83%A8.png)
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。
