To grasp the function of an audio endpoint, one must first distinguish it from the physical device. A pair of USB headphones is a physical device; the “Speakers (USB Audio Device)” listed in Windows sound settings is the endpoint. Formally defined in Microsoft’s Windows Driver Kit (WDK), an audio endpoint represents a single, logical connection point for an audio stream. A single physical device can have multiple endpoints. For example, a gaming headset with both playback (speakers) and recording (microphone) functions will appear as two distinct endpoints: one for output and one for input. Similarly, an HDMI monitor with built-in speakers creates an audio endpoint that the operating system treats independently from the video signal. This abstraction allows Windows to manage each audio function separately, applying unique volume levels, effects, or formats to each endpoint regardless of the shared physical connection.

When you connect an audio device to your computer, Windows creates an audio endpoint for that device. The endpoint acts as a bridge between the device and the operating system, allowing you to control and configure audio settings. Here's a step-by-step overview of the process:
