Just got word from our friends at Station-Drivers.com that they've snagged a new Creative Sound Blaster Live & Audigy Driver version 512.12.4.285 WHQL from IBM for Windows 2000/XP. I expect that these need some editing to be able to install. Almost all drivers since .253 were not compatible with the Soundblaster Audigy software including SurroundMixer, AudioHQ etc. Alternatively Audigy users might opt for the latest official .383 drivers.
