I have a Ranger vii mobo with Logitech Z506 5.1 speakers running win 10. Many times the rear speakers stop working over the last couple of years and just get noise coming from them. I have in the past been able to solve this and get them working. I have spent the last 4 hours or so today trying to get them to work. I have tried various Realtek drivers including the driver for my mobo on Asus download site. I am now on version 6.0.8934.1 which I believe is the latest version. I have googled numerous supposedly solutions, none of which seem to work now. I believe the problem lies with win 10 updates.
You need Realtek Audio Drivers (HDA - ASUS ROG/PRIME/TUF MB) from this drivers thread. Follow scrupulously your INSTALL process with cleanup step, for the next drivers packages that I would release, you will can directly follow the UPDATE process.
Note (in order to choose correctly the install/update process to use) : You have a ASUS ROG SS1 motherboard.
The configuration of the audio channels (Stereo, 5.1, etc.) is done via Realtek HD Audio Manager/SupremeFX (via tray icon or via Control Panel). The configuration of the Surround/Upmix is done via Sonic Studio II.
