The microphone is not detecting any input.
HIstory:-
I have installed garuda linux many times on my laptop from time to time but there is always this issue of microphone not detecting any input. Audio for some reason works fine with zoom but doesnt work for any other software.

What i have tried(i might not remember everything coz i have been trying to solve this problem for a long time):

  1. I made sure that pulseaudio and pipewire are not conflicting
  2. I dont have any dependencies issue
  3. I have currently have pipewire as the like server for the sound part of my laptop
    4.I have made sure that nothing is muted in alsamixer using f5
  4. I have made sure that Analog Stereo Duplex is selected in pavucontrol
  5. I have only pipewire-media-session not wireplumber
  6. Output for arecord -l

10. I think i read in one of the forms that booting into linux lts might fix the issues i have tried and it hasnt worked.
These are the forums i remember visiting

  1. Pipewire stealing my mic? - #8 by Exanime
  2. Internal microphone stopped working in lenovo laptop
  3. Internal/external Microphones do not receive sound - #3 by c00ter
  4. PipeWire - ArchWiki
  5. No system audio when joining a discord channel

When searching the Arch wiki for this model, it showed that very similar models (that also have a “stereo” mic) have issues. PulseAudio/Troubleshooting - ArchWiki

"No microphone input on Acer Aspire One and Lenovo Ideapad 310-15ISK/330-15ARR

Install pavucontrol, unlink the microphone channels and turn down the left one to 0.

Some applications (e.g. chromium) can change microphone levels causing the same issue, a workaround is to remap stereo input to mono and use the remapped device as default."

I tried this solution.

I dont have a concrete answer as to what is happening but i think keeping either left or right channel at 100% and then altering the other channel's input to somewhat of 60% is giving me some like reaction to my voice. Like now when i say something the graph goes up and comes down to a stable when not speaking, so its like a 50 - 50 workaround you have to see whats good for your system. But one thing thats sure is unlock the channels
.

I tried remapping the channels but i have pipewire and so it was not that useful, but i think it will work fine for now.
Thanks

The problem is back again this time with static noise, i tried to redo the solution probably thinking this might just be because of restarting but it is very hard to get that back.

I solved it with QasMixer. I leave you the steps to follow answered in the following link: https://github.com/pop-os/pipewire/issues/8

I'm glad to hear you fixed your issue @TiVP, but this is not Pop_OS and we do not use the apt package manager here.

For anyone who wants to try @TiVP's QasMixer package, it is provided by QasTools:

sudo pacman -S qastools

A three-month bump is a bit much for a support thread so I'll go ahead and wrap this one up here.
