I want to connect a sound card to my laptop with headphone and mic audio. I also want to connect a male 3.5mm jack to male 3.5mm jack from my PS4 controller into the laptop so that I can get audio through the same headphones I already have plugged in, and then listen to PS4 audio and whatever my laptop is playing. How would I go about doing this? Could I get another sound card and use that also? Do I need a mixer? Thanks for any answers in advance.
