答案1

更新 11.05.20

我今天全新安装了 Ubuntu 20.04.1。我不需要应用下面提到的更改。我没有遇到任何声音或视频问题。一切都正常。由于安装可能不适合所有人,我将在下面保留对我有用的原始答案。一如既往,希望这个答案能对某人有所帮助。

原始答案如下:

@Raffa 和 @Terrance - 你们两个都 +1。你们的评论帮助我指明了正确的方向。

好的,现在它已经可以正常工作了,下面就是我实现的方法。我尝试按照这篇文章中的建议更新 grub:

但它破坏了我的视频。登录时屏幕会变黑,并且永远不会恢复。这促使我对 snd_hda_intel.dmic_detect 进行了一些额外的搜索,并找到了以下文章:

文章底部有以下内容:

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

然后添加以下行。

options snd-hda-intel dmic_detect=0

现在它对我来说 100% 正常工作。我的所有硬件都已识别并处于最佳状态。我希望这对某些人有帮助;谢谢大家。

答案2

抱歉我低估了你,但是你确认你的用户属于群组audio吗?

groups youruser

如果没有,你可以添加

sudo adduser youruser audio

答案3

声卡无法识别。我的解决方案。我从已安装的操作系统中的 18.04 升级到 20.04,但没有声音。“虚拟输出”。我尝试了所有我能找到的解决方案,但都没有成功。我最终决定从新制作的 Live USB 进行全新安装。确保在安装过程中打开扬声器,以防它使声卡更明显。全新安装后一切正常。我尝试重新安装也没有成功。最好的建议是下载一个新的 ISO 并制作一个 Live USB。
