未检测到麦克风

未检测到麦克风

由于某种原因，我无法再在声音应用程序/配置应用程序中看到我的麦克风。选择框是空的。

内置麦克风。联想 X1 rev 9。

在此处输入图片描述

但是这列出了一个设备：

为什么系统无法识别这个麦克风？

谢谢

传统的英特尔驱动程序可能永远不会完全支持该芯片组。

以下是我最终修复此问题的方法：

  1. 用 pipewire 替换 pulseaudio。请按照此操作指南操作。https://linuxconfig.org/how-to-install-pipewire-on-ubuntu-linux

  2. 安装 firmware-sof-signed 包。替换旧的英特尔驱动程序。

    $> sudo apt 安装固件-sof-signed

我现在有可以正常工作的麦克风（因为这个笔记本电脑有多个麦克风，所以是复数麦克风）。输出设备可以像以前一样正常工作。
