Ubuntu 18.04 更新后音频消失

我已经在我的 Thinkpad X1 Carbon 第 7 代上使用 Ubuntu 18.04 一段时间了，音频工作正常，但是在昨天运行了一些更新之后，似乎声卡在我今天早上重新启动时停止了工作，这可能相互关联吗？

dmsg 输出：

答案1

所以，回答我自己的问题。经过一番挖掘，我终于设法让我的音频再次工作。在找到这个帖子后https://bugs.archlinux.org/task/64720snd_hda_intel.dmic_detect=0我尝试按照本指南临时添加启动参数：如何添加内核启动参数？验证它是否有效。它解决了我的问题，我现在永久添加了密钥，并且修复似乎在重启后仍然存在。

答案2

我在 Ubuntu 19.10、Thinkpad X1C7 上遇到了同样的问题。此外，我无法再关机。我尝试了你自己的答案，但没有帮助。

因此我按照如下指令将内核从 5.3.0.42-generic 回滚到 5.3.0.40-generic： 如何在错误更新后降级内核（16.04）

重启后，它就起作用了。
