Heloo sir my mic is not working why.please telme this problem solowed

Hello sir,

are you sure the mic is plugged into the mic jack on your computer, not the speaker or line-in jack?

did you check to make sure your mic is the selected source for recording? (control panel--> settings--> sounds & audio -->audio tab)

did you check to make sure your recording volume is high enough? (volume button, same screen)

this should be enough to advance your situation
