The hardware consisted of a Cirrus Logic 7212 CPU (ARM720T at 74 MHz), 1Mx32 (4 MB) of EDO RAM, and either 512k×16 or 256k×16 (1 MB or 0.5 MB) of NOR flash used to boot. Audio output used a Burr-Brown PCM1716 DAC that drove line outputs, the headphone jack, and a Tripath class-D digital audio amplifier for speakers.

Another goal of UAA is to provide better support for multi-channel audio in Windows so that, for example, multi-channel WMA Pro audio streams can be played without special driver support. UAA is intended to be a complete replacement for developing WDM Audio Drivers; however, in some cases it may be necessary for an otherwise UAA-compliant audio ...
When the sound card uses a custom driver for use with the system supplied port class driver PortCls.sys or implements a mini-driver for use with the streaming class driver, applications can bypass the KMixer completely and use the kernel streaming interfaces instead to directly interact with audio driver and reduce latency. Windows 98 includes ...

SciTech SNAP (System Neutral Access Protocol) is an operating system portable, dynamically loadable, native-size 32-bit/64-bit device driver architecture. SciTech SNAP defines the architecture for loading an operating system neutral binary device driver for any type of hardware device, be it a graphics controller, audio controller, SCSI controller or network controller.
Wolfson's chipsets were known for delivering high-quality sound that matched or surpassed the offerings of well-established manufacturers like Cirrus Logic. After replacing Wolfson's chip with a chip from Cirrus Logic there was a minor decline in Apple's iPod sound quality when connected with high-end audio gear despite the improved board design.
