Through Windows Update I got drivers for my Logitech surround system being Digital Audio (S/PDIF) (High Definition Audio Device).With luck you can find outdated drivers from 2017 (note that Microsoft/Softpedia provides drivers as latest as from 2019).
as the absolutely latest which is inconsistent with Softpedia (since that site provides even newer drivers). I am having quite some trouble with finding the latest Realtek high definition audio device drivers for my Windows 10 system as the latest available driver version varies depending on which site you search on.
