我的笔记本电脑内置麦克风和声音输入不起作用。笔记本电脑型号为华硕 X555UJ。Ubuntu 版本是 16.04。我尝试了 Ubuntu 声卡故障排除页面中提到的故障排除步骤 (https://help.ubuntu.com/community/SoundTroubleshooting)但都无济于事!
以下是来自 pacmd 的我的声卡信息。

答案1
我有同样的笔记本电脑和同样的问题。我在网上没有找到任何永久的解决方案。但是,您可以手动激活 3.5 毫米插孔:
在终端中输入:
alsamixer
现在,您可以将扬声器音量设置为 0%,将耳机音量设置为 100%。我编写了 2 个脚本,可自动切换耳机和扬声器音量:
这个是耳机用的:
#!/bin/bash
amixer set Headphone 100%
amixer set Speaker 0%
这是给演讲者的:
#!/bin/bash
amixer set Headphone 0%
amixer set Speaker 100%
然后我把这些脚本赋予了键盘快捷键。快捷命令是:
gnome-terminal -e "path-to-script"
总比没有好。
我会继续寻找问题的真正解决方案,如果找到,我会在这里分享。
答案2
我在这个帖子上找到了解决方案 耳机插孔不工作?
解决方案是,
在终端中运行以下命令:
gksudo gedit /etc/modprobe.d/alsa-base.conf 向下滚动并将以下行添加到文件末尾:
#Keep snd-pcsp from being loaded as first soundcard
options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=dell-m6-amic
然后,保存、重新启动并使用耳机和扬声器测试声音。
