Dell G3 3579 - Microphone not working

Hello,

My Laptop's mic doesn't seem to be working when I use Microsoft Teams. I have checked all the settings on the Teams as well as the default settings of my laptop. I have never faced this issue before. I have also updated my Sound Drivers, BIOS, Chipset as well. Yet, I am facing the same problem. Could you please look in and support me on this?
