Internal microphone not working on any distro, any kernel


Hello everyone, this is a problem that I have been trying to solve for a while. I've tried a lot of distros and versions (Ubuntu, Mint, MX, Elementary, Deepin,
My problem is, basically, that Linux is not capturing my voice, either because Linux can't detect my mic or the voice.
I've done many tests, and I have discovered some of the most unusual things.
First of all, my PC is a laptop (Lenovo ideapad 320) and my sound card is HDA Intel PCH (Realtek Generic).
I have to say my mic works perfectly on my Windows, even when I install any distro in a virtual machine, it works perfectly too.
Then, the case is that, in general, what happens is that Linux detects the microphone as hardware, but the only thing it emits is noise.
I have tried everything I have found on the internet. Solutions with "alsamixer", "pavucontrol", ...
The only one that usually works is to silence the right in "pavucontrol", but even so that suddenly fails.
In fact, here comes the strange thing: In Ubuntu 18, the "solution" of pavucontrol works almost perfectly, it detects the input of the microphone and that of the headphones when I connect them, but in Ubuntu 19 it no longer detects the headphones, and there if I dont know what to do.
Something even stranger was the case of "Deepin", which perfectly recognized the input with the pre-installed Deepin recorder, but it does not recognize me in the other applications ...
So... what more can I do? Why virtual machines works fine but it doesn't in the real one? Why happened that about Deepin?
I'm desperate with this topic.

Some things to check.

Is it seen by the system? - dmesg
Is a module loaded for it? - lsmod
Is it muted? - alsamixer
Does the software you are using need to be configured for your mic? - Menu>Edit>Preferences

I'm on MX Linux right now.
dmesg output and lsmod output are attached in .txt because of their size.
And about alsamixer, everything is ok, nothing is muted.
