Headset connected to laptop but no sound?

Hello people have just connected my headset to my laptop and have found that I have no sound my laptop has only jack and my headset so synonymous sound should actually come or you have to adjust something before

On the laptop there's the possibility to switch on the sound output "mute", check it out first. Mostly a combination of "FN" + "F1-F12", different depending on the laptop.

Of course, look to see if driver for sound is installed.
