If you are connecting your PC to a 5.1 or 7.1 surround sound AV receiver via an optical cable, use digital output. Your receiver likely has a much better DAC and amplifier than your motherboard. realtek digital output better
Digital file ➔ Motherboard DAC ➔ 3.5mm audio jack ➔ Speakers/Headphones.
This process completely bypasses two major weak points of onboard audio:
Whether is "better" depends entirely on your hardware setup. It is not a generic "high-quality" mode; rather, it is a specific connection path for digital audio equipment. Core Comparison Realtek’s onboard clock is not studio-grade
It is better for the home theater PC user who wants to send a 5.1 Dolby Digital signal to a vintage receiver without the video latency of HDMI. It is better for the musician who needs a click track with zero delay. It is better for the streamer who is tired of the ground loop hum caused by their GPU and USB microphone sharing a power rail.

To understand why one output might be better than the other, you must understand the Digital-to-Analog Converter (DAC).
The Realtek Digital Output's benefits are most apparent when you pair it with high-quality source material and software that can utilize it properly.
Windows cannot always control the volume of a raw digital stream. When using Realtek Digital Output, you often lose the ability to adjust your volume using your keyboard hotkeys or the Windows taskbar slider, forcing you to use the physical knob on your external speakers or receiver.
