The Ezycap - Audio Windows Driver is a software driver that enables the audio functionality of an Ezycap video capture device (commonly used for capturing video and audio from sources like cameras, game consoles, etc.) on a Windows-based system. This driver ensures that the computer recognizes the audio input from the Ezycap device and allows the proper communication between the device and the system.

Ezycap devices often come with a built-in audio capture feature (e.g., capturing audio from an HDMI signal or from a composite video input). Without the correct driver, the system may not detect or properly process the audio input from the Ezycap device.
