Ubuntu 18.04音频在更新后消失

Question

我已经用Ubuntu18.04在我的Thinkpad X1碳第7代上使用了一段时间，音频工作正常，但是昨天运行了一些更新之后，当我今天早上重新启动时，音频卡似乎已经停止工作了，这可能是相互关联的吗？

dmsg输出：

[   32.624585] skl_hda_dsp_generic skl_hda_dsp_generic: Unsupported HDAudio/iDisp configuration found

Answer 1

所以回答我自己的问题。经过大量的挖掘，我终于成功地使我的音频再次工作。在找到这个线程https://bugs.archlinux.org/task/64720之后，我尝试临时添加引导参数snd_hda_intel.dmic_detect=0，方法是遵循本指南：如何添加内核引导参数？来验证它是否有效。它解决了我的问题，我现在永久地添加了密钥，并且在重新启动之后，修复似乎仍然存在。

Answer 2

我在Ubuntu19.10上，Thinkpad X1C7上也有同样的问题。而且，我再也不能关机了。我试过你自己的答案，但没什么用。

因此，我将内核从5.3.0.42-泛型回滚到5.3.0.40-泛型，如下说明所示：如何在更新错误后降级内核(16.04)

重新启动后，它成功了。
