Creative appear to be making false claims and mislead their own Audigy users by saying that the ALchemy project supports X-Fi only, and if you wish to restore functionality on Audigy, you must buy the 'ALchemy Audigy Edition'. By doing this, they are effectively selling a Hotfix that offers features the users already paid for. The truth is, Audigy owners can download the original ALchemy (X-Fi) and use it successfully. Creative is misleading the public and trying to make money out of this ALchemy scam. These users already have paid a lot of money (in some countries as much as $300-600) for Creative’s Audigy cards, so why should they pay them again!? We’re all aware about Creative’s poor software and customer support, but this time they really crossed the line.
