I would like to buy a headset that I can use with this sound card. The desk controller of the sound card has two inputs for jack, one for headphones and one for the microphone. Is it possible to connect a headset that only has a jack output (combined microphone and headphones)? And if so, where do I have to connect the headset to the controller? Or do I need a headset that has two separate jack outputs (microphone and headphones)?
