The AMD CIR (Consumer Infrared) Driver is a software component that allows your Windows operating system to interface with infrared (IR) hardware on your AMD-based system. This IR hardware is often used for remote control functionality, enabling devices like media centers, home theater PCs (HTPCs), or other consumer electronics to communicate with your computer via infrared signals.

In simpler terms, the AMD CIR driver helps your computer receive signals from a remote control, enabling features like controlling playback on media software, adjusting volume, or interacting with the system from a distance using an IR remote control.
