In previous Windows releases, the entire audio stack ran in Kernel space. Vista will put an end to this. "The first (and biggest) change we made was to move the entire audio stack out of the kernel and into user mode. Pre-Vista, the audio stack lived in a bunch of different kernel mode device drivers, including sysaudio.sys, kmixer.sys, wdmaud.sys, redbook.sys, etc. In Vista and beyond, the only kernel mode drivers for audio are the actual audio drivers (and portcls.sys, the high level audio port driver)."

In fact, this is not even an old idea : everybody wants to bring the whole audio stuff out of the kernel, since the beginning. The problem is that it brings a lot of latency issues.
Audio in the kernel is not a problem, as long as the drivers do not contain run-time errors.
