In order to develop Universal Audio Drivers, use the following tools: Visual Studio 2015: New driver settings allow the “Target Platform” to be set to “Universal” to create a multi-platform driver. APIValidator: This is a WDK tool that checks whether driver is universal and highlights calls that need to be updated. The latest UAD Powered Plug-Ins software installer, which includes all drivers and files necessary to use the Apollo, is available here.The installer file is downloaded to the disk location specified in your web browser's preferences.

The Microsoft Universal Audio Architecture (UAA) enables audio devices that comply with the architecture to rely entirely on the operating system for driver support.

To be UAA-compatible, a PCI audio adapter must conform to the Intel High Definition Audio specification, which is the successor to the Intel Audio Codec '97 (AC'97) specification. Unlike AC'97, Intel High Definition Audio (Intel HD Audio) standardizes the bus controller, in addition to the codec devices and the serial interface link (the link that connects the controller to the codecs). The UAA design guidelines for Intel HD Audio devices contain additional requirements that are not part of the Intel High Definition Audio specification. Windows Vista provides complete driver support for UAA-compliant PCI audio adapters.

To be UAA-compatible, a USB audio device must conform to both the USB audio specification and the UAA design guidelines for USB audio devices. USB audio devices can make use of the USBAudio class system driver (Usbaudio.sys), which is supplied as part of Windows. By definition, a USB audio device that is compatible with the USBAudio class system driver in Windows is UAA-compliant.

To be UAA-compatible, an IEEE 1394 AV/C audio device must conform to both the relevant IEEE 1394 specifications and the UAA design guidelines for IEEE 1394 AV/C audio devices. IEEE 1394 audio devices can make use of the AVCAudio class system driver (Avcaudio.sys), which is supplied as part of Windows.

For more information about the Microsoft UAA initiative, see the Universal Audio Architecture white paper.

For a list of related specifications for USB and IEEE 1394 audio devices, see USBAudio Class System Driver and AVCAudio Class System Driver.

Important Microsoft has released version 1.0a of the Universal Audio Architecture (UAA) High Definition Audio class driver for Microsoft Windows. The newer release supports the High Definition Audio and modem implementations that are known to Microsoft as of August 1, 2004. This is the second version of this driver and supersedes this hotfix. We recommend that you install version 1.0a of this driver. For more information about version 1.0a of this driver and about how to obtain it, click the following article number to view the article in the Microsoft Knowledge Base:

888111 Universal Audio Architecture (UAA) High Definition Audio class driver version 1.0a available for Windows XP, Windows Server 2003, and Windows 2000

INTRODUCTION

This article describes the first release of the Universal Audio Architecture (UAA) High Definition Audio class driver for Microsoft Windows. This driver is designed to work with the following versions of Windows:

  • Microsoft Windows Server 2003

  • Microsoft Windows XP Service Pack 1 (SP1)

  • Microsoft Windows 2000 Service Pack 4 (SP4)

This release supports the High Definition Audio and modem implementations that are known to Microsoft as of March 19, 2004. The package will not work on High Definition Audio implementations that are disclosed to Microsoft after this date.

More Information

A supported feature that modifies the default behavior of the product is available from Microsoft. However, this feature is intended to modify only the behavior that this article describes. Apply this feature only to systems that specifically require it. This feature might receive additional testing. Therefore, if the system is not severely affected by the lack of this feature, we recommend that you wait for the next software update that contains this feature.
If the feature is available for download, there is a 'Hotfix download available' section at the top of this Knowledge Base article. If this section does not appear, contact Microsoft Customer Service and Support to obtain the feature.
Note If additional issues occur or if any troubleshooting is required, you might have to create a separate service request. The usual support costs will apply to additional support questions and issues that do not qualify for this specific feature. For a complete list of Microsoft Customer Service and Support telephone numbers or to create a separate service request, visit the following Microsoft Web site:

More Information

The new UAA describes a class driver architecture for computer audio solutions that are supported in Microsoft Windows operating systems.
An audio device that is UAA compliant can rely completely on the operating system for driver support. Therefore, the hardware vendor does not have to supply a custom driver for the device. Microsoft plans to supply UAA class drivers for the following classes of audio device in Windows Server 2008.

  • USB Audio

  • IEEE 1394 AV/C

  • High Definition Audio

Driver

A High Definition Audio device complies with the Intel High Definition Audio specification. A High Definition Audio device connects to the PCI bus or to the PCI Express bus. This High Definition Audio device can reside on an internal audio card, or it can be part of an integrated motherboard chip set. The update that is described in this article supports the spring 2004 Intel initial hardware release of High Definition Audio-compliant solutions.
The third-party products that this article discusses are manufactured by companies that are independent of Microsoft. Microsoft makes no warranty, implied or otherwise, regarding the performance or reliability of these products.
The advantages of UAA over the current audio industry solution, AC’97 Audio Codec, include the following.

For users

  • Simpler installation of audio peripherals

  • Increased system stability

  • Easier installation of audio drivers

  • Increased performance

  • Glitch-free audio

  • Increased security for protected content

  • Reduced requirement for vendor-supplied drivers

  • Reduced requirement to upgrade drivers

  • Guaranteed basic audio support for UAA-compliant devices

For OEMs and hardware manufacturers

  • Reduced software development, testing, and support

  • Reduced exposure to product support calls and to product returns

  • Easier phase-out for products at 'end of life'
