Asus India — Asus vivobook 14 ultra/ mic issues

I have bought the asus vivobook 14 laptop ultra in flipkart on a month ago, exactly on april 1. The laptop was perfect at its conditions. Also its performance also so good. after some couple of weeks, when i was in a online meeting, i found that mic isnt working after loading the page it was resolved. then i thought that it might be some website issue. then it continued for many times. due to pandamic situation, i find difficult to resolve it in a service centre. but i thought of raising complaint in this manner. without even a year, im facing such a issue and i bought this laptop without anyones wish even my parents, so i cant handle this situation. please do respond or say some solutions. i even have a warrenty tooo. hope you reply. i also add up a image of my issue.
