Earphone Problem Laptop

[sharoonaftab2]

So, I have a Dell laptop LATITUDE E6430 ATG suddenly whenever I plug in the earphones the sound does not come from earphones but from the built-in speakers. I have tried with several different earphones but nothing seems to be the solution. Though all those earphones work correctly on my phone and other laptops. But no sound comes from a specific laptop (From Earphones). What could be the problem? Is it of hardware or software?

When you plug it in, click on the sound icon in the system tray, and then click on the name of the speaker listed at the top. Does it show the headphones as being an option?
