After checking many good reviews I got the new Creative SoundBlaster X-Fi Fatal1ty ExtremeGamer, only to find that they have a multi-purpose jack that can be used for digital audio out, or line in, OR mic. Well, not so great for those of us using both spdif out and a mic. I went back to my Logitech USB Desktop Mic, that seems to work fine with the system, but I'm disappointed with their engineers on this one.
