What is the Crystal CS4624/CS4630 WDM Interface Windows Driver?

The Crystal CS4624 and CS4630 are audio chips produced by Crystal Semiconductor (now part of Cirrus Logic). These chips are often used in sound cards and integrated audio solutions for computers. The WDM (Windows Driver Model) Interface driver refers to the software that allows the operating system (Windows) to communicate with and use the audio features provided by these chips.

The WDM interface is a driver model introduced by Microsoft for Windows, allowing hardware components to work with applications that support the WDM framework. This driver would allow your Windows system to interact with and manage the audio input and output functions provided by the CS4624/CS4630 audio chips.
