This library is a C++ implementation of the Zircon Audio Stream and Ring Buffer driver protocols suitable for use in simple audio drivers where the codec and DAI functionality are contained in the same driver.
It handles most of the boilerplate of publishing and shutting down devices, handling client connections, and FIDL-serialization/de-serialization/validation of protocol messages as well as enforcing some of the protocol state requirements.
Generally speaking, users of the library should only need to subclass the SimpleAudioStream, provide details about their capabilities during Init, then respond to messages in their overloaded methods. Hopefully, this allows authors of simple audio drivers more time to focus on banging on registers, and less time on manually validating messages and protocol state.
