[Windows Central Question]

How can I make sounds come out of any device I plug into the headphone port?

1st, we have no idea what device you are talking about.
2nd, most devices, by default, disable onboard sound once headphones are plugged in. If you think about it, that is the point of headphones.

If you are not getting sound period after you plug in your headphones, it's possible your headphones, if they also have a built in mic, has the pinout setup in a way that doesn't like the device you are using, but again, we have no idea what you are using. a laptop, desktop, phone? what brand/type/model of laptop, desktop or phone? Contrary to popular belief, we aren't all psychic :)

HP ProBook 450 G2 running Windows 10 on a 64 bit operating system with 3.88 GB of 4.00 GB of memory available.

any external sound devices will not work when plugged into the headphone port. I have tried multiple speakers and headphones. I have downloaded the newest sound drivers. I have uninstalled and reinstalled the drivers and reset the settings to factory. Nothing I have tried will work.

Does that information help you help me? (OH it's got Intel CORE i5 for a processor)

Do you have an icon that slightly resembles a megaphone down by the clock? There is nomally the standard Microsoft speaker/megaphone icon, but a lot of motherboards come with Realtek audio chips on them, and that has a separate app, which may need configuring. If you have this, you should be able to open the app and configure any/all ports to work however you wish. See below where the arrows show the standard Microsoft audio app on the task bar, and the Realtek app above. Opening the Realtek app presents you with the more advanced options you may need to get your outputs working the way you need. If you don't have a Realtek app, then maybe you'll have something similar from another manufacturer...
