Title pretty much says it all. I have an Asus Xonar DG 5.1 audio card in my computer, and I want to try out a surround sound headset, but the only problem is the vast majority of gaming headsets are 7.1, and the few that are 5.1 are either absurdly overpriced, have relatively bad reviews, aren't available in my country (would have to get them shipped to Canada from the US, and international shipping on electronics tends to be rather expensive) or just aren't very pretty to look at. So what I want to know is whether or not it's possible to use a 7.1 headset on a piece of hardware that only supports 5.1? Naturally, I would assume it would work, but the extra channels wouldn't be used, but can someone give me more detail? I saw a pretty good deal on a 7.1 Razer Kraken headset (Black Friday and all), but I don't want to buy something that might not work with my setup.
