Latest Realtek HD Audio Driver Version

Hi guys. Can anyone help me figure out what is going on.

I have an Asrock Z370 ITX Gaming (ALC1220) board, and I have been trying to install the latest HDA and UAD driver without success.
The last working package was the one specified on the board's official Asrock site (old 8454 with Creative build).

If I install the latest HDA drivers (ex. 8730) I have no sound on my board's output jacks.
If I try to install UAD, the setup throws an error saying that none of the packages were supported.

I have even tried the build listed a few posts above for another Asrock board, that is very similar to my board's specs.

To switch from HDA to UAD you will always get an error unless you totally nuke anything to do with HDA: Realtek Audio Console REQUIRES a Realtek HD (UAD) Driver!!

I have followed your instructions to the letter, but I have not been able to resolve the issue.
UAD simply refuses to install with error code -0001.
Also I was expecting at least some leftover files to be found by the search (and driver) utilities, but there were no leftover Realtek files nor drivers, nor registry keys :S
Its as if I did a clean install of the OS, but it still refuses to install.

Something that also bothers me is, why would the recent HDA packages install successfully, report that the device is operational, and display everything as they should; but not be able to reproduce any sound. Even the windows "test" audio device button, throws an "unable to play sound" error.

Also check in control panel sound and make sure the correct setting is set to default


also look at the properties.

UEFI HD audio is enabled.

Currently I am on the default Windows 10 build 1903 HD audio drivers (since I don't have any luck with Realtek), so my control panel properties do not reflect the reference image. When the outdated version (supplied by Asrock) was installed and working, it was set up like your image.
