and design. The Cirrus Logic chip makes the sound! The cards sounds like an Audigy 4 and not like Audigy SE. The SE drivers work, but they do not make the sound, this does the cirrus logic converter. The calculations are done by the CA106 and by software, what nowaday with Dual Cores and more doesn't matter. Important is the DAC and they are the same with the other X-Fi and the Audigy 4. So the X-Fi is actually an Audigy 4 refurbished.] X-Fi MB X-Fi MB is a software solution that enables basic X-Fi features on computers with integrated audio into an X-Fi device. It requires some degree of driver support from the audio hardware manufacturer. X-Fi MB is commonly bundled with motherboards and computer systems, and is comparable to an X-Fi XtremeAudio. Bundled with some Asus and ASRock motherboards, the X-Fi MB is sold as X-Fi Supreme FX and is actually a standard Analog Devices integrated HD audio codec paired with X-Fi MB. The X-Fi features are implemented entirely in the software. Other hardware vendors sell the X-Fi MB solution simply as Sound Blaster X-Fi Integrated Sound. X-Fi MB is available in different versions e.g. X-Fi MB, X-Fi MB2, X-Fi MB3 and X-Fi MB5. The current version available on select laptops and desktops is X-Fi MB5. A non-OEM version of X-Fi MB3 was sold by Creative Labs but is no longer on the market. X-Fi MB3 provided an effective software version of a full X-Fi card and was also provided with a version of Alchemy that works with non-Creative sound cards to restore legacy EAX effects.
