18.04 on Lenovo Thinkpad comes out, you can not see the sound card

I've been fighting for a week for nothing I did myself. The sound comes out after an automatic update.

I posted this several days ago.

On one occasion, I was able to list the sound card, but then it disappeared again. Now I'm back to Simulated output and there is no sound.

Please help. This has been the worst problem I've had with Ubuntu. It looks like an elephant in the room and does not get enough attention.
