In the context of the HDA specification, a "Node" often refers to the abstract representation of a functional block within the codec (e.g., DACs, ADCs, Mixers). However, within the ACP hardware context, the HDA Node manages the discovery and configuration of these widgets. It exposes the topology of the connected codec to the operating system driver.
