Computer doesn't recognize headphones

[capri9]

I was trying to listen to some music through my earphones when i realized my computer doesn't recognize them, although they were already plugged in. They worked perfectly fine yesterday. all i had to do was right clicking the speaker icon, selecting "playback devices" and choosing the headphones. Please give me a simple and understandable solution since I'm not really good with computers.

Thanks

Have you tried rebooting the PC and trying it?
