[SOLVED] Lenovo Laptop microphone does not work

[sanimint]

I am using a lenovo laptop. I am running dual boot windows/linux on it.
I am a linux noob and i installed Linux mint recently. Everything seems to work fine except the microphone. I did not have this problem when i was using Ubuntu.
I tried many things on this forum including muting the right channel on pavucontrol but nothing seems to work. I use the laptop for online classes and stuff and because of the microphone issue, i'm stuck with windows.
Kindly help me solve this issue. I'm posting the output of pacmd list-sources

Thanks Deepak. I followed the advise in the link you shared. Installed alsa-tools-gui package:

Code: Select all

sudo apt install alsa-tools-gui

and changed the settings as shown below.

This think has been bugging me for over a month. Thanks a bunch, really appreciate your help.

You are welcome.
