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 components (version 6.0.9275.1 for HDAUDIO devices and 6.0.9287.1 for INTELAUDIO devices) 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 components (RTKVHD64.sys and RTAIODAT.DAT) with their 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 6.0.9276.1 for HDAUDIO and 6.0.9288.1 for INTELAUDIO are completely unsupported.
Force updater is now capable of defeating PNP lockdown protection. This is required to successfully force update from WHQL codec v6.0.9264.1 or newer. Due to force updater needing to elevate to SYSTEM to accomplish this, the elevation agent used may be blocked and/or quarantined by anti-malware software. If this happens force update fails.
Realtek Audio Control app
This release installs Realtek Audio Control app v1.35.271.0 via store, but a newer offline installation package v1.36.273.0 is also available. Installing Realtek Audio Control app from offline package doesn't require admin rights as it installs per user like any Windows store app. Also make sure Windows is set to allow side-loading Windows store apps or installation from offline package will fail.
