Internal mic does not work properly with chat apps

[ehsan]

Hi, I have a strange issue with internal mic of my lenovo ideapad310 laptop. This mic works with no promlem on windows 10.
It woks very well when I use the sound recorder. But when I want to chat with skype or google meet the other person could not hear my voice. I used test audio of skype and google meet and I found that my voice quality is terrible there. The voice is too low with some noise.
I have installed alsamixer and here is the information that it shows:

And here is more information from the terminal by some commands.

I don't know if this will help

But what I do is install pavucontrol sudo apt install pavucontrol, after the installation I open that and on the las tab "configuration" I select the "stereo duplex" option.

Then in the tab of the input devices it should show the microphone and you can configure easily the volume there.

For the noise I use a pulseaudio module, to "install" it, modify the following file; /etc/pulse/default.pa

At the last lines you should see a line that say
### Modules to allow autoloading of filters (such as echo cancellation)
And after that there is a some modules auto loaded, add a new line:
load-module module-echo-cancel

To finish, restart your pc and try your microphone

Thanks. Unfortunately this solution does not work.

Wow. Thanks a lot that solution works.
I edited this file /etc/pulse/default.pa as described there.
And this is how my input devices look like:
