Internal microphone makes static noise and doesn't pick up my voice

I use Acer Swift 3 SF315-52 and is currently using Ubuntu 20.04 LTS.

Initially, my internal microphone doesn't produce any noise but produces noise now after editing /etc/modprobe.d/alsa-base.conf

options snd-hda-intel model=laptop-amic enable=yes

But the noise produced is just loud static noise, and the microphone doesn't pick up my voice at all. I'm also dualbooting Windows 11 and Ubuntu, and the microphone works perfectly on Windows, so it's most likely not the problem on my microphone.

Here is the output of pacmd list-cards:

I have also tried many other things, such as alsamixer, pavucontrol but nothing seems to be solving my problem. Here's what alsamixer looks like if needed: image

And also what the sound sounds like: sound

So, does anyone know what the problem is and how to solve it? I've been having this problem from the start and I've had to use Windows for voicecalls, online school, etc, and I would be very glad if this problem is fixed.

Ìf you need any other outputs, I would gladly provide them and edit this post.

Any help is appreciated.

Thank you!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
