我有一台全新的惠普Omen 17t笔记本电脑。我加载了Ubuntu20.04,没有声音。我尝试了这里建议的步骤:
如果有人能提供任何建议,我们将不胜感激。作为参考,我在下面列出了lshw的输出。

我今天重新安装了Ubuntu20.04.1。我不需要应用下面提到的更改。我没有任何声音或视频问题。一切都起作用了。由于安装可能不适用于每个人的盒子外,我会留下原来的答案,对我在下面工作。像往常一样,希望这个答案能帮助到别人。
@Raffa和@Terrance - +1给你们两个。你的评论帮助我找到了正确的方向。
好的,我现在让它起作用了,这就是我是如何到达那里的。我试着按照这篇文章中的建议更新grub:
不过,这是我的录影带。登录时屏幕将为空白,永远不会返回。它引导我在snd_hda_intel.dmic_detect上进行一些额外的搜索,并找到了以下文章:
在文章的末尾有以下几点:
sudo gedit /etc/modprobe.d/alsa-base.conf然后将下面一行添加到其中。
options snd-hda-intel dmic_detect=0现在对我来说是100%的。我所有的硬件都被识别出来了。我希望这对某人有帮助,谢谢大家。

如果我低估了你,我很抱歉,但是你确认你的用户属于这个组音频吗?
groups youruser如果不是,您可以将它添加到

声卡认不出来。我的解决方案。我在安装的操作系统内从18.04升级到20.04,没有声音。“虚拟输出”。我试过了所有我能解决的办法,但没有运气。最后,我决定从一个新制造的Live中重新安装。确保扬声器在安装过程中打开,以防声卡更显眼。在新安装之后,一切都正常。我也没有运气,试着重新安装。最好的建议下载一个新的ISO并制作一个Live。
