![]() The driver uses a "virtual audio device" instead of an actual hardware-based adapter and highlights the different aspects of the audio offloading WDM audio driver architecture. ![]() The driver uses WaveRT and audio offloading for rendering devices. Some of these audio devices are embedded (speakers, mic arrays) in the system while others are pluggable (headphone speaker/mic, Bluetooth headsets speaker/mic). The TabletAudioSample project demonstrates how to develop a WDM audio driver that exposes support for multiple audio devices. The sysvad solution file contains the following projects. These are working implementations with source code that can serve as a starting point for writing a custom driver for a proprietary audio device. ![]() The SYSVAD driver highlights many important features of the WDM audio architecture. ![]() System Virtual Audio Device Driver Sample (SYSVAD) Feedback In this article SYSVAD Audio Sample ![]()
