Unofficial Realtek UAD Generic 6.0.9126.1
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.
This release comes with an update for Realtek Audio UWP app. Open Windows Store and do a check for updates to get Realtek Audio Control 22.214.171.124 right away or wait for Windows store to pull it.
On systems without Windows Store use the offline installation package of Realtek Audio Control app.
what Realtek audio driver version are you using, DirtyShady?
and is the Realtek audio driver a UAD/DCH version? Realtek Audio Control UWP app only works with UAD drivers, not HDA FFxx (non-UAD) drivers.
I get a Gigabyte branded Realtek Audio Control app (v126.96.36.199) from MS store when installing the 9126 UAD Gigabyte driver on my Gigabyte motherboard.
