The WDK is constantly being updated with Windows Vista relevant
documentation. We have only one doc writer and literally hundreds of
documentation work items for him to write about. The highest priority
topics (those with most requests) are typically documented first. We are
currently working on improving the System Effect infrastructure
documentation.
WaveRT miniports are in use on 95% of all Windows Vista Logo compliant
systems and it is a Premium Tier Logo requirement to make use of that
driver model when the hardware design permits - such as with HD Audio
based audio devices.
The WaveRT documentation in the white-paper you link to below is
current. The AC-97 WaveRT sample in the WDK may not have all the
functionality outlined in the documentation implemented.

Subject: [wdmaudiodev] Vista audio documentation
I was just wondering if anyone knows if there's any intention to
document the Vista audio system in the WDK (or anywhere else for that
matter). What's currently in the WDK really only speaks about the way
things work in XP, and there have been many gems of information I've
gleaned from this list (such as the PKEY_AudioEngine_OEMFormat and
PKEY_AudioDevice_SetupPreferred INF registry keys) that have been
invaluable in getting my drivers to work satisfactorily under Vista.
There's nothing in there about endpoints, and even WaveRT is only
mentioned briefly in passing, with just a link to the preview document
at http://www.microsoft.com/whdc/device/audio/wavertport.mspx.
Are we even supposed to be using WaveRT in commercially released
drivers, or is this still considered experimental? The latest (September
2007) release of this document still describes itself as a preview and
states:
