not sure if this is the right forum to put this in but anyway; I want to be able to hook my ATH-AD500x's and modmic into my PC and xbox one at the same time without having to keep unplugging them when i want to play on my PC or xbox. I currently have a sound blaster z in my pc. For my xbox i plug my headphones and mic into a Y splitter cable that is plug into the stereo headphone adapter that is plugged into the controller. I've been doing some research and it seems you can do it with a sound mixer and some adapters and cables. But i don't know which mixer and cables to buy. And i also don't know if its possible to hook my xbox to the sound mixer with only the hdmi as a sound output.
