Currently there are 4 diffrent drivers:
1.) One from Creative itself, latest version v0.3b (April'99) (gone, but they claim to be working on another driver that will incorporate OpenAL.)
(Rated: **)
2.) One Open Source GPL developed driver, which is updated almost every day.
It's based on the source code of the binary V0.3b release, but has advanced a lot since then.
(Rated: ****)
3.) Free driver support by ALSA, which also has OSS emulation and Midi synth support
(Rated: ****)
4.) Commercial OSS driver support by 4Front
(Rated: **)
