UAA seeks to resolve problems by putting forth a standardized interface which audio devices can follow, ensuring that the device's capabilities will be recognized and used effectively by Windows, without the need for additional drivers or custom control panels. It also provides a reasonable assurance

The goal of the Universal Audio Architecture is to solve a very common problem in older Microsoft Windows products, that of inconsistent support for audio. Due to the lack of a common system by which audio devices could describe their capabilities to the operating system, not to mention a lack of
