Windows Driver Model WDM audio drivers make use of the kernel streaming KS components, which operate in kernel mode and are part of the operating system. Hardware vendors should make several design decisions before beginning development of a Windows-based audio hardware device. The first decision is whether to design an audio device that requires a vendor-supplied custom driver.

The vendor does not need to provide a custom driver for a UAA-compatible audio device. However, if a vendor-supplied custom audio driver is necessary, the vendor must choose whether the driver should be designed to work in conjunction with the PortCls system driver Portcls. PortCls is the correct choice for most audio adapters.

When designing a custom adapter driver that uses PortCls, the devices on the audio adapter are made available to applications using WaveRT. Two additional decisions involve how to present the adapter topology and pin data ranges to audio applications. The topology is a logical map of the data paths and control nodes in the adapter circuitry. The data ranges specify the data formats that the devices can support in their wave and MIDI streams. Both decisions affect how the devices on the audio adapter appear to applications.

In making all of the previously mentioned decisions, the hardware vendor must weigh the value of performance enhancements against the cost of implementing them.

Another consideration is whether a particular solution can be made to work on a number of products in the Windows family. This section provides an overview of these issues as well as references to more detailed documentation about specific topics.
