Headphones work in monitor, but not PC

[Ike0]

Hey guys,
I have a 2x BenQ GL2450
When i try and plug headphones into my PC, it doesn't work.
The monitor speakers see to be put first and plays even when my headphones are plugged in.

If you want t manage audio devices (search for it in the start menu or you can go there from the control panel). Then right click on the headphone jacks from your PC and hit set as primary device(or something similar). Boom your computer will try to use those first instead of your monitors.
