Realtek produces hundreds of codec models (e.g., the ALC892, ALC1220). Each chip has different capabilities regarding bit-depth (24-bit vs 32-bit), sample rates (96kHz vs 192kHz), and signal-to-noise ratio (SNR). The specific driver contains the "definition tables" for that specific chip. It tells the Operating System exactly what the hardware is capable of, preventing the OS from sending formats the hardware cannot decode.
Historically, Realtek drivers were monolithic—specific to the motherboard model. Recently, Realtek shifted to the model. what does realtek audio driver do

The Realtek Audio Driver is what turns your computer’s generic audio hardware into a fully featured sound system — enabling everything from basic headphone output to advanced surround sound, mic processing, and jack auto-detection. Without it, your PC would still produce sound (via a basic Microsoft driver), but you’d lose most of the features that make Realtek audio chips useful.
Sound falls out of sync with video playback during streaming or gaming. 🔄 How to Keep Your Driver Updated
