Acer Swift Edge's internal microphone is not working

I recently bought Acer Swift Edge. I started using Ubuntu 22.04.2 LTS and when I was using Discord, I noticed that my laptop's microphone was't working (but worked properly in Windows). The audio outputs were fine. These are the results of output commands:

inxi -A:

Here are some screenshots: alsamixer pulseaudio

Note: These might effect the results from guides I followed, none of them work:

1. Sound Input device (microphone) not working

2. https://www.reddit.com/r/linuxhardware/comments/xzxkef/realtek_alc256_sound_card_issue_fix/

3. https://www.youtube.com/watch?v=Vz6jDUyn7S0

I ran out of options. Are there anyway to fix this problem?

Thanks in advance.

PS: I stumble to this forum. People had the same problem as I do. Although it's from 2018 - 2019, was it resolved in Linux v5?
