Ubuntu 18 suddenly won't find output sound hardware

Asked by Jim Hefferon on 2020-04-03

I have Ubuntu 18, MATE, on a Dell. Suddenly, two days ago, I cannot get sound out. (I would be delighted to contribute $20 to whatever you would like to get a solution to this.)

The Control Center > Sound > Ouput says I only have "Dummy Output". In fact, I have an intel onboard sound card.

Here is the information that the Sound Troubleshooting Guide asks for.

I should mention that I am very naive about the kernel and stuff like that and pretty much just install a stock Ubuntu Mate. I'm really not sure where:

[ 4.732355] snd_hda_core: loading out-of-tree module taints kernel.

comes from.

Do you use UEFI? This seems to relate to this message? Is the system a single boot (Ubuntu only)?

Jim Hefferon (jhef11) said on 2020-04-07:

Andrew,

Many, many thanks for your help. My answers are below. But, before them I'll say that this morning the problem is solved.

I assume there was an update that took effect when I rebooted this morning. I changed nothing.

Thank you again. I answered the questions because who knows if if might help someone someday.

> Do you use UEFI?

I believe that I do. It was supplied by my employer that way.

> Is the system a single boot (Ubuntu only)?

It is. Ubuntu 18 where the only major variation is Mate.
