Ubuntu 20.04 - No sound (2023)

I installed Ubuntu 20.04 LTS and I noticed that I have no sound, I am using Lenovo Legion Y520-15IKBN. I want to continue using Ubuntu and learning about Linux, but having no sound is a kind of a deal breaker for me and going back to Windows is my last resort.

I have tried every Google result, and every "solution" but nothing is working. I also apologize if a thread like this already exists, but I was really digging around ask Ubuntu and I couldn't find any solutions.

Thank you for your help, and sorry for my English :)

First I want to say that when I plug in my USB headphones, audio is working just fine, the problem is with laptop's built in speakers and microphone.

Here is what I know:

I tried to purge pulse, alsa, reinstall them, but nothing seems to help.

When I type alsamixer, I get this:

cannot open mixer: No such file or directory

Here is the link of alsa-info script that I run on my laptop.

dmsg output is this:
