Main Microphone doesn't work - Redmi Note 8 Questions & Answers

Hi.
I bought my phone around 3 weeks ago and suddenly the main mic stopped working . It doesn't matter if it's in calls or video recording or sound recording , it doesn't work.
When I record something with no sound around , afterwards when I listen to it , it's kind of a noise like paper on wood . Also the secondary mic Wich is on top of the phone is working but in very low volume.
I have tested both in the testing program (the one that opens up after taping 5 times on kernel) and none of them passed the test.
Right now I'm at work but when I get home I try and upload some recordings ، for now I just wanna know what's what. . thanks
Edit : a 15 second recording
Also a video

Microphone problem with video recording

If I record a video in quiet environment there's so much background noise in the playback that I have to turn the volume down...is this normal? I've tried with 2-3 apps and it's always the same. I can't understand why with calls and audio-only recording there's no problem. I bought the nexus a few days ago on amazon so I'm still able to send in back
no1 has ths problem?

help, main mic is broken. how to set up sub mic for calls?

Hello everyone, a while ago I dropped my phone and now the main mic is broken (the one near the charging port). So I can't record audios or make calls without using a headphone with a mic. BUT WHEN I RECORD VIDEOS THERE IS SOUND. I think that's because of the noise cancelation mic(the one on the upper right side of phone) For some reason it's activated during the video records and captures the sound.
How can I force my phone to use secondary microphone all the time? So that I can make calls and record sounds without changing the primary microphone.
well, I'm not a programmer but I have been trying to edit audio_policy. conf and audio_policy_configuration.xml files.
Apparently there are 2 input sources for microphones. built-in mic and built-in back mic. I have tried deleting these or somehow ' disabling' them. but nothing happened. I can still capture sounds while recording videos but the very same damn microphone wouldn't work while recording voices.
How hard is it to simply disable the main mic and use the noice cancelation mic as the main one? I'm sure you programmers can figure it out better than me ??
I'm facing the same issue, have you found any hack for that ?
Any luck bicho2015? My main microphone died on my Pixel 4 and I would like to reroute to the other 2 built-in mics.
