Motherboard: Gigabyte Aorus Z390 Ultra , BIOS v F8
Audio (on-board): Realtek ALC1120-VB codec
Steps already taken:
updated all drivers and chipsets to most current
confirmed in apps list, control panel, Startup panel, and Search that there is no Realtek Audio Manager installed
disabled all audio controllers that are not Realtek
uninstalled all Realtek audio drivers (including checking the box to delete associated driver) in Device Manager
rebooted and reinstalled a number of versions of the latest drivers from both the manufacturer website, Aorus, and Microsoft Catalogue, and even the R282 version from 2017 from Realtek
No matter what I do, the Audio Manager does not install and I therefore have no way to re-task the line-in jacks for 5.1 channel sound.
My questions are:
1. where can I get a complete installer that will properly install both driver and Audio Manager
2. what is the name/version of the drivers I need
3. is the process described above adequate and if not, please describe in detail the necessary process
