Okay, so I am building a gaming PC and I want to get the Sennheiser 598s and the Asus Xonar Essence STX sound card. This is a 7.1 sound card, but I am wondering if you get true 7.1 virtual surround by just plugging the headphones into the 3.5 jack? I don't think you do. And if not, how do you get 7.1 surround from the card? Do you have to use the optical out port? If so, how to connect the headphones to the optical? I'm really new to this so please be easy on me. If anyone can, please just explain this whole thing to me, but any answers are appreciated. Also, anyone who can give me a suggestion on a sound card besides the Essence STX, please do. I am looking for a card with great surround and sound quality in general. Thanks.
Edit: I have come to find out that S/PDIF can only carry up to 5.1 surround, so how is it possible that this card would be 7.1? It has a ; (this is copied from Amazon)Main stereo RCA out, headphone out, SPDIF out, line in (Mic in) Other frount audio header, Aux in, S/PDIF header. Which one of these jacks can do 7.1?
I need this question answered fast so sorry if I asking to many questions.
