麦克风不工作 | Zenbook 型号 ux32la 编解码器 Conexant CX20751/2 | ALSA | ubuntu 20.04

我看到了很多关于麦克风不工作我研究了所有这些。这是麦克风使用中常见的错误/问题Ubuntu。有许多补丁和程序可以修复该问题,但是并非适用于任何型号。我尝试了其他帖子中的所有解决方案,但都没有成功。所以,基本上我写这篇文章,内心深处希望有人可以帮助我,但无论如何,对于一个足够专业的人来说,也许可以在功能上为这样的模型提供补丁/怪癖/更新。 :(

然而,如果有任何好心人可以帮助我或者有好主意,我会很乐意尽我所能并乐意解决这个问题!

以下是有关专业化和我所做的事情的屏幕和数据:

输出设备

我试过:

  1. 以多种不同的方式配置 /etc/modprobe.d/alsa-base:
sudo subl /etc/modprobe.d/alsa-base

添加了此

options snd-hda-intel model=asus-zenbook

和这个

options snd-hda-intel model=MODEL position_fix=1

和这个

options snd-hda-intel model=OTHER MODELS SUCH AS DELL 

这一切都没有成功

  1. 我通过插孔/耳机连接了外部麦克风,但这个外部麦克风不能正常工作

  2. 我使用应用程序 wo mic 通过蓝牙连接外部麦克风(手机作为麦克风),并录制了一些质量较差的音频。但是它确实录制了。

这就是我所做的。

问候并感谢所有的帮助!
