The AMD Audio CoProcessor Extension is a driver component that helps to manage and improve audio performance on systems with AMD processors, particularly those equipped with integrated AMD Radeon graphics. This driver extension typically works in conjunction with the AMD chipset and provides additional support for certain audio features, such as HDMI audio, integrated audio processing, or other audio functionalities specific to AMD hardware.

The AMD Audio CoProcessor Extension is most commonly associated with:

• AMD integrated graphics: For systems that use integrated graphics (i.e., the GPU built into the AMD APU or CPU), this extension may be involved in handling HDMI or DisplayPort audio outputs.
• Advanced Audio Features: It may improve audio handling or provide enhancements for certain high-definition or multi-channel audio output scenarios.
