First day I bought my live! to replace my MX300 (Vortex 2), (Aureal was a month away from officially closing it's doors), I noticed two things: One, the highs were muted, and Two, the drivers were crap. None of the effects could be used, they were too exagerated, you had a basic reverb that sounded halfway decent, the rest was just noise for kids to play with. (I can't believe any musician would take that seriously.) Now the Aureal drivers were crap too, but they were smaller and less offensively crappy.
The rest of the misc crapware was just too unbelievably bad to even keep on my system [I want to] [Delete this crap][and get rid of this stupid sound card]. I bought the thing for 4.1 sound compatibility with my Hollywood Plus DVD decoder, which I have since sold, my latest problems with the drivers not even installing since I bought the Radeon was just too much, so I sold it. Looking for a Philips card, worse case, the drivers may not be better, but then again, they can't get any worse.
Creative drivers in general are crap, from video cards to web cams to sound cards, I've just about tried them all, they are facinated with Window regions and making round brown guis, they just don't care about basic functionality.
Hardware incompatibilities are not the sole reason people are saying the Live! is crap, it's just the last straw. IMO, going with the defacto standard in sound cards can only compensate for so much grief before you want to be a part of changing that standard. Competition is good.
