No sound after i plug in my earphone into laptop?

When i plug in my earphone into my Lenovo laptop, Windows 10 only recognized it as microphone and not earphone and my computer become silence.

It looks like your jack is 7pin type 3.5 mm jack
that automaticaly turns off the computers internal speakers
when something is plugged in jack
Maybe
The speaker in earphones is damaged

Did you tried plugging it in other devices

Did you plug it into the plug for speakers or headphones instead of for microphones? I know my laptop has two ports and only one works for my headphones
