Partial WHQL notice
Due to Realtek not providing regular updates to HDXRTU.CAT, HDXRT.inf, HDXRTSST.inf and HDX_GenericExt_RTK.inf, it wasn't possible to make a Realtek UAD Generic package for old systems that is 100% WHQL compliant. To workaround this setup installs latest generic WHQL compliant codec component (version 6.0.8924.1) with hardware support application, audio effects and service components taken from latest version and then a force updater is used to replace the old codec component (RTKVHD64.sys and RTAIODAT.DAT) with its latest version.
Due to absence of valid and updated copies of HDXRTU.CAT, HDXRT.inf, HDXRTSST.inf and HDX_GenericExt_RTK.inf (or equivalents) new hardware IDs introduced since 6.0.8825.1 are at most partially supported and those introduced since 6.0.8925.1 are completely unsupported.
