no sound on output jack

I get sound out of my internal speakers, but no sound when I plug ear phones into the output jack. I've got a new HP laptop model - 17-BY1053DX with Windows 10.

Thanks.

If new it should still be in warranty [usually 1 year from purchase], best to get the seller involved.

That is a combo jack. Sometimes you need to try different headphones.
