The AMD Audio CoProcessor is a Windows driver that supports audio functionality for certain AMD-based systems, particularly those with integrated AMD processors that include an audio co-processor as part of their architecture. This co-processor is designed to handle audio tasks and work with the system’s primary audio driver (typically Realtek, VIA, or others) to provide enhanced or integrated audio features.

In some cases, this driver may appear in Device Manager under Sound, video, and game controllers, or in System Devices. It is typically required for AMD-based systems where the integrated audio chipset relies on an AMD-specific co-processor to manage certain audio tasks, such as decoding or encoding audio streams, or offloading audio-related tasks from the CPU.
