Headphone Audio Problem

[Kindly]

When I plugged my earphone to my laptop, only the microphone works, but the audio can be heard from the laptop itself. I can't set the headset as default, I don't know what's wrong with it. Do anyone knows how to fix it?

Thanks!

Make sure that the headphone/mic is not for an apple product. I think they use the same connector but not the same way.
