没有音频输入和输出 Ubtutu 20.04

我的 Ubuntu 20.04 突然停止输出音频和接收输入。现在，如果我使用蓝牙耳机，我可以听到音频，但“内部声音”和 USB 耳机都无法被识别。

uname -a输出：

Linux Lab 5.7.4-050704-generic #202006181331 SMP Thu Jun 18 13:33:57 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

设置->声音如下所示： 在此处输入图片描述

在无法确定出了什么问题之后，我运行了这个脚本，我发现 snd-hda-intel 模块肯定没有加载。

wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh

输出为这里

我已经尝试重新安装 alsa 和 pulseaudio，但没有任何改变 :(

编辑：添加更多信息

  1. 当我运行sudo lspci音频部分时是：00:1f.3 Audio device: Intel Corporation CM238 HD Audio Controller (rev 31)

  2. 我的电脑是 MSI GL62M-7RD

编辑2：添加输出aplay -l

哇。我以为没有声音，但蓝牙在这里也可以用。我有一台华硕 c436f Chromebook。目前无法在 Chomeos 上运行虚拟机，所以我将我的 go 加载到 18.04。它无法识别任何硬件。20.04 识别的硬件刚好足够使用。我尝试了以前版本 Ubuntu 的所有修复程序，但都没有成功。运行命令时你得到了什么sudo lspci？我得到了很多，但该输出的主要候选是 00:1f.3 多媒体音频控制器：英特尔公司设备 02c8。根据我的研究，这似乎是一个内核问题。我也在用最新的。如果我在其他地方找到解决方案，将在这里通知您。您的硬件平台是什么？

编辑并仅供参考：帮助击败 uefi 的 Mrchromebox 回复了此问题：

这是意料之中的事，只是内置的编解码器/放大器（扬声器/麦克风）无法正常工作。从这里快速浏览一下，似乎驱动程序已包含在内，因此可能只需要从 ChromeOS 复制 Alsa 配置/UCM/固件即可。但我需要仔细看看
