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 the next major desktop Windows release. That version of Windows is code named "Longhorn."
- USB Audio
- IEEE 1394 AV/C
- High Definition Audio
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"
