Headphone and interface trouble

maesl

The interface I use to power my microphone and headphones is the Native Instruments Komplete Audio 1, and I want to connect my gaming headset (I'll be switching to studio headphones soon, don't worry).

However, this isn't working as intended. When I plug the 6.35mm jack into the headphone jack of the interface, I get sound, which seems great. But my system stops receiving sound from the XLR line input until I disconnect the headphones. I've seen recommendations about "routing" the outputs and inputs correctly, but I'm unfamiliar with this term and unsure how to fix it. I hope someone in this great community can help me with this dilemma. (Gain and input/host knobs were adjusted correctly before taking this picture)

Thanks for your awesome help! I managed to find out that, the issue was not on me, nor on the interface. The issue was voicemeeter, that somehow got everything messed up. After shutting down voicemeeter everything worked awesome. There is just a single problem, i have to use voicemeeter, i run a ton of vst plugins via lighthost. Is there a fix that lets me use voicemeeter again? Or can you recommend me a simmilar software like voicemeeter (Paid or free) that has patch insert features?
