"Digital Output (Realtek)" refers to the software interface for transmitting uncompressed PCM or compressed multi-channel audio (e.g., Dolby Digital, DTS) via a digital connection (S/PDIF) from a Realtek audio codec. Unlike analog outputs (3.5mm jacks), this output bypasses the system’s digital-to-analog converter (DAC), sending raw digital data to an external receiver, soundbar, or DAC.
