The new UAA audio architecture is a driver architecture designed for audio solutions for personal computer use. The system is supported by Microsoft Windows operating systems.

An audio device compatible with UAA can entirely rely on the operating system to support drivers. Therefore, the hardware provider cannot supply a specific driver for USB Audio, IEEE 1394 AV/C and High Definition Audio.

High definition audio devices are compatible with the Intel High Definition Audio specification. These devices are connected to PCI or PCI Express bus; they can reside on an internal audio card, or be a part of a chipset integrated to the motherboard components.

The third-party products mentioned in this article comes from Microsoft independent companies. Microsoft makes no warranty, implied or other, regarding the performance or reliability of these products.

The advantages of UAA architecture compared to the current standard audio solution are its ability to enable an easy installation of audio devices/drivers and the improved system stability. Apart from that, it can also eliminate problems related to sound and performance and improve security and protection. Meanwhile, it also reduces the need for specific drivers and upgrade drivers.

Microsoft UAA Function Driver for High Definition Audio supports Adi 1983, Adi 1986, CMedia 9880, Conexant Waikiki, Sigmatel 9770, Sigmatel 9772, Realtek Content Creation Bay and Realtek High Definition Audio.
