全新 Inspiron 5509 上没有麦克风

全新 Inspiron 5509 上没有麦克风

我正在尝试使用板载麦克风进行视频会议。我在 alsamixer 或 pavucontrol 中没有麦克风调整。

我确信这台笔记本电脑有麦克风,只是我没看到。这就像驱动程序问题,但我找不到型号信息来开始追踪驱动程序。

已安装的驱动程序:

如何打开全新 Inspiron 5509 上的麦克风?

我试过:

sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio

但这并没有什么用。厚颜无耻地寻找也没有用。

以上操作不会创建声音文件。

答案1

这解决了问题。具体来说是他的第二次更新。

修复网址

gedit /etc/modprobe.d/alsa-base.conf

add
blacklist snd-hda-intel
blacklist snd-soc-skl

reboot
