I have an Asus Maximus VIII Ranger motherboard running Windows 10 Pro. Yesterday, I updated the bios and installed a new version of the Realtek audio driver that was there on the Asus website. Audio playback was present until today evening, when the sound from the speakers stopped. I looked at the list of Playback Devices and the Realtek device was missing from there. Device Manager has an yellow exclamation mark against 'High Definition Audio Controller' under 'System devices', where the error is:
This device cannot start. (Code 10)
{Operation Failed} The requested operation was unsuccessful.
When I reinstall the Realtek drivers, installation proceeds successfully, but the files that it claims to copy into Program Files and Program Files(x86) disappear immediately after installation completes, and the Realtek device does not appear in the list of playback devices.
I refreshed and reset Windows 10, but the issue still persists. I even tried to install the older Realtek drivers, and the drivers from the Realtek website (instead of the Asus website) but it made no difference. What may be the issue with the drivers?
