The following C++ code example demonstrates how to enumerate audio endpoints using the MMDevAPI:
When an app calls IMMDevice::Activate(IID_IAudioClient, ...) : mmdevapi audioendpoints
For a developer or system engineer, the "feature" is implemented via COM interfaces: The following C++ code example demonstrates how to
To document the internal workings, dependencies, and functional boundaries of MMDevAPI as it pertains to — logical representations of audio devices (e.g., "Speakers (Realtek High Definition Audio)"). "Speakers (Realtek High Definition Audio)").
