 The driver architecture consists of the following:
-- Hardware Device Interface (HDI) adapter: implements the audio HAL driver (HDI adaptation) and provides hardware driver capability interfaces for the audio service (frameworks). The HDI adapter provides interface objects such as Audio Manager, Audio Adapter, Audio Control, Audio Capture and Audio Render.
-- Audio interface lib: works with the audio driver model in the kernel to control audio hardware, read recording data, and write playback data. It contains **Stream\_ctrl\_common**, which is used to interact with the audio HDI adapter layer.
-- Audio Driver Model (ADM): serves the multimedia audio subsystem and enables system developers to develop applications based on scenarios. With ADM, codec and DSP device vendors can adapt their driver code based on the unified interfaces provided by the ADM and implement quick development and easy adaptation to the OpenHarmony system.
-- Audio Control Dispatch: receives control instructions from the library layer and distributes the control instructions to the driver layer.
