My microphone volume is very low

Question

I have the newest ubuntu installed with everything up to date. It's a laptop so there's an integrated microphone in it which does work under windows. It's made by Intel. Alsamixer says HDA Intel PHC. I tried to adjust the microphone in alsamixer but it changes nothing and resets everytime i restart the laptop. It can barely record my voice when im speaking next to the mic very loudly.

Run alsamixer and press F5 to see all the controls. Search if You have one named Mic Boost - make sure it is unmuted - set to 00 instead of MM. — Michal Przybylowicz, Aug 27 '19 at 15:23
It's always muted. If i unmute it nothing happens and becames muted again if i restart the laptop — hzoltan01, Aug 27 '19 at 15:56
Do You have option Auto-Mute in alsamixer and is it disabled ? — Michal Przybylowicz, Aug 27 '19 at 15:59
It's enabled by default. But nothing changes when i disable or enable it — hzoltan01, Aug 27 '19 at 17:55

Install pavucontrol:

sudo apt install pavucontrol

Launch it by running pavucontrol on the command-line, and adjust the volume of the mic in the "Input Devices" tab. You can even go above 100%, although I don't recommend it as it can lead to distorted sound:
