In the Recording tab, select your Mic and then click on "Set Default" button to make it primary device. This way, your mic should also work.

The level bar rises once you speak into the mic.

As far as why it may not work, my best guess is that on the MoBo's back I/O panel, you have different 3.5mm jack than you have at the front I/O of your PC case. Older 3.5mm jacks had single purpose, either send sound (headphone jack) or receive sound (mic jack). Newer 3.5mm jacks can both send and receive sound inside the same jack.

This is especially true when on the MoBo's back I/O panel, you have dedicated 3.5mm jack for headphones (usually colored lime green) and for mic (usually colored pink). If this is the case, you'll need this splitter cable (or similar) as well if you want to use your headset at the MoBo's back I/O panel,

This is my Motherboard :


i can confirm that the Sound Jack is colored Green and the Microphone Jack is Colored Pink

The Sound Jack is plugged to green and the sound is working ,
The mic jack is plugged to the pink but it's not working , i tried to unplug the sound jack and keep only the microphone jack to see if it works but it didnt .

I highly doubt that it would be software issue within your OS since if it were, your mic wouldn't work in the front I/O panel jack either. And since you have fairly old MoBo in use, it wouldn't be a wonder that some of it's features have degraded up to the point of failure. To confirm that, plug the known to be work mic (other than your headset) to the mic port on your MoBo and look if it works or not.

And like i said to you, most likely the mic port on the back of your MoBo is broken due to the old age of your MoBo. To test that, use second, known to work microphone, other that the one included with your headphones.

If something is broken, no matter how badly you "want" it to work, it isn't going to work, until it's either fixed or replaced.

Well, external USB connected/powered sound card would do but internal PCI-E based sound card would give you far better audio quality. But since sound cards are niche market only used by audiophiles and i'm not an audiophile, i can't say which sound card (internal or external) would be the best one to go for.
