So, I was browsing my motherboard drivers page and there seems to be some sort of Christmas present: 2008/12/24 Realtek Function driver for Realtek Azalia audio chip (This audio driver together with Creative Utility enableds X-Fi crystallizer, X-Fi CMSS-3D,EAX®ADVANCED HD4.0) http://www.gigabyte.com.tw/Support/Motherboard/Driver_Model.aspx?ProductID=2843 http://www.creative.com/oem/products/software/x-fimb.asp Now the driver is Vista 32bit and I'm on 64bit, so I haven't tried it. But it sound like you get some "X-Fi" stuff along with Audigy 2/4 EAX. My Audigy 2 (with audigy 4 drivers) did EAX 4.0. The creative site pdf says: System Requirements o Windows XP x32 o Windows Vista x32 o Windows Vista x64 o Supported HD-Audio Codec So is this for all supported HD audio chips (what ever they are) and if so, will it cost something? Would seem so as it says "Sound Blaster X-Fi MB utility (30-day trial version)". Realtek page didn't have any mention about this, haven't gone through creative pages yet.
