Dear Sir,
The UAA initiative requires a Designed for Windows Vista audio device to
be compliant with certain standardized audio technologies. A PCI add-in
device as with any other Windows friendly audio device such as
integrated audio solutions and external bus audio devices must be
compliant with one of the standardized, freely licensed under RAND
licensing audio technologies supported by Vista class drivers under the
UAA initiative. The last 2 years there has been nothing stopping you
from creating audio devices that would be compliant and obtain a Vista
Logo according to the one of the required technologies.
What you can't do is get a Vista Logo using a proprietary audio
technology that cannot be supported by Windows natively through the UAA
class drivers. This is part of the It Just Works initiative and will
provide great benefits to Windows users in the years to come. The
benefits of the UAA initiative are discussed in the documents linked
below.
The DRS program has changed name to the Unclassified Program and cannot
be used by devices that expose themselves as audio devices to the
Windows OS. An audio device must pass the Logo tests for that device
class and hardware compliance (at the register level) is part of the
test suite.
There is another way to sign your drivers (that has nothing to do with
the Logo program) so that they can load on Windows and you can read more
about that here:
http://www.microsoft.com/whdc/system/platform/64bit/kmsigning.mspx
The UAA initiative has been the topic of every Windows Hardware
Engineering Conference (WinHEC) since we first talked about it in 2002
and the device requirements of the UAA initiative have been published
unchanged in the Windows Vista Logo program documents since draft .45
April 2004.
You can read more about the UAA initiative here:
http://www.microsoft.com/whdc/device/audio/default.mspx
Specifically:
http://www.microsoft.com/whdc/device/audio/UAA_HWdesign.mspx
and
http://www.microsoft.com/whdc/device/audio/PinConfig.mspx
and
http://www.microsoft.com/whdc/device/audio/HD-aud_PnP.mspx
and for a taste of what our WinHEC messaging has consistently been:

2295b40c8/TW04062_WINHEC2004.ppt
We do realize that there are/will be products in the market that for
some reason does not implement the hardware behavior required by the UAA
initiative but for these types of devices there is currently no Windows
Logo program.
The common integrated PC audio device solutions we expect to be Logo
compliant cover 97% of the audio device market and our goals with the
UAA initiative align closely with that mass market. Specialized,
high-end low market share solutions (relative to the approx. 177 million
PCs sold a year) is not the main target of our initiative but since it
is perfectly possible to implement these devices in a Logo compliant
manner and since communication about and evangelism of this initiative
has been going on for the last 4 years there is no exception if you want
the Designed for Windows Vista Basic or Premium Logo on your device.
You may send any questions you have about this to uaa @ microsoft.com.

Hi
I am write PCI audio device driver for windows. According Windows Vista
Logo
Program: Windows Vista Logo Program Client System Requirements, Version
3.0,
Draft Revision 0.8, Audio device is compliant with one of the
appropriate
technology specifications supported by the UAA initiative (AUDIO-0009).
Does
its means the PCI Audio device can't get Vista logo? If I need Vista
logo
for my PCI Audio device what can I do? Can I submit it by DRS ? Thanks.
BR,
Tzung-Dar Tsai
