我是 Linux 新手,运行 Ubuntu 20.04.4 LTS,没有其他操作系统。我发现我的输出音频是假的,没有找到模拟声卡。我不确定是什么原因。这些是命令输出:
$ alsamixer
$ pavucontrol
$ lspci -v | grep -A7 -i "audio"

我努力了 :
...以及我找到的其他建议,我甚至不记得链接,但仍然不起作用。
另外,我无法访问 BIOS 上的“高级”选项卡,以查看我的声卡是否因制造隐藏/禁用而意外被禁用。
请帮助我。
非常感谢您的答复。

我的 Minis Forum GK41 上的 Xubuntu 23.04 也存在同样的问题。我尝试了很多解决方案,最终通过此链接解决了:https://www.linuxuprising.com/2018/06/fix-no-sound-dummy-output-issue-in.html
基本上你需要编辑两个文件,如第二部分指南。
编辑/etc/modprobe.d/alsa-base.conf
snd-hda-intel dmic_detect=0
以 root 身份并在此文件末尾添加选项。编辑/etc/modprobe.d/黑名单.conf
snd_soc_skl
以 root 身份在文件末尾添加黑名单。完成这些更改后,重新启动系统。
准确地说,现在音频输出可以与 HDMI 配合使用,仍然无法使用我的音频插孔,但是嘿...这就是我需要的!
