Audigy owners will get ALchemy, for a low cost, later this year
Microsoft Windows Vista features a new audio stack, which completely revamps how the operating system communicates with audio devices. The new audio stack, dubbed
Universal Audio Architecture
, or UAA, requires companies to develop new drivers. Hardware accelerated audio devices are treated as an independent device, separate from the audio output capabilities of a sound card under Windows Vista.
The way UAA handles hardware DSPs is a problem for Creative Labs when it comes to delivering hardware acceleration for DirectSound 3D and EAX algorithms. Earlier this year Creative Labs launched its
that enabled hardware-accelerated audio on Sound Blaster X-Fi owners. ALchemy translates DirectSound 3D and EAX calls into OpenAL, which can still take advantage of the DSP hardware.
Creative Labs left Sound Blaster Audigy owners in the dark, in regards to hardware-accelerated audio in Windows Vista. However, Creative Labs stated ALchemy support for Sound Blaster Audigy 2 and 4-class products are to be determined depending on demand. Due to demand, Creative Labs has
begun ALchemy development
for Sound Blaster Audigy-series sound cards.
Creative Labs expects to have ALchemy for Audigy sound cards later this year. It does not appear as if ALchemy will be free to current Audigy owners. Nevertheless, when the cards are ready, Creative Labs “hopes to offer this product as a low-cost upgrade to interested Audigy owners.”

MS kicked everything out of the kernel primarily for security reasons. Elimintating driver based crashes from any source is a side effect of that.
Locking down the kernel was a smart move for security, but it does require new drivers to be writen for almost everything. The kernel still isn't completely secure, but its a hell of a lot better then it was when you could load anything into it.

You meant DRM. But wait, that's going away, and besides, anyone running Vista on a virtual machine can get at it anyway.
