It looks like chinese website MyDrivers has found a leaked or ripped version of the Audigy 2 software and drivers. They are offering two download links: the complete set at 179Mbyte and drivers only at 24Mbyte. According to MyDrivers the new revised driver and software suite also works on original Audigy and SoundBlaster Live! cards. They also seem to produce a little richer and warmer sound says MyDrivers.

However it is unknown to which extent Live! and Audigy users can utilize the Audigy 2 software and if there are problems when using it (bugs?). Full downloads available at this site.
