Abstract
Systems and methods for audio streaming in a computing device are described. In one aspect an interface to an adapter driver is provided. The adapter driver is associated with an audio device. The adapter driver and a wave real-time (WaveRT) port driver associated with the computing device use the interface to configure direct access by a client of the computing device and by the audio device to a cyclic buffer. The direct access is for rendering and/or capturing an audio stream. The direct access is independent of any copying by a port driver on the computer system of the audio stream to any buffer.
