No audio from headphones

I plugged my headphones into my PC and can't hear anything. It's weird because when I go to the volume mixer I could see the levels going up and down but I can't hear anything..

My headset is plugged into a splitter via 3.5mm Jack and then the green and pink 3.5mm Jack are plugged into my motherboard in there respectable place
