I would have thought on the HP Laptop there would be a built in microphone you could use to record. Play the backing into headphones and set the internal microphone to record. That way you could record the voice without the backing.

Not the way I’d do it, but in a pinch it should work. Better yet would be to lash out on a USB Audio interface that will allow you to do very much more.

Just a thought
