What is Realtek Digital Audio Output

Realtek digital audio output refers to the digital audio signal that is decoded by the Realtek audio chipset and output digitally over an interface like HDMI or S/PDIF optical. This allows you to connect external digital audio devices like soundbars, AV receivers, etc. that support digital inputs.

Benefits of using Realtek Digital Output:

  • Higher audio quality as the signal remains in digital domain end-to-end
