The (Audio CoProcessor High Definition Audio Node) is a virtual hardware component found in modern AMD-based systems, such as Ryzen laptops and NUCs. It acts as a bridge between the AMD Audio CoProcessor (ACP) and the standard High Definition Audio (HDA) controller, enabling advanced audio features like digital microphone arrays and low-power audio processing. acp hda node
