Realtek should develop a package with only 64bit files with Windows signatures for their Realtek High Definition Audio driver installation.Realtek has released its 2.82 HD Audio driver compatible with Microsoft’s Windows 2000, XP, Vista, Windows7, Windows 8, Windows 8.1, Windows 10 x86/圆4 Driver. Realtek’s present driver adds support for new ALC codecs: ALC891, ALC667, ALC236, ALC256, and ALC293. It seems software by ASUS / Realtek are supplying 32bit software files without signatures which is causing the problem. This time the fix worked – and advised the device was working correctly. Ran the trouble shooting against the audio again, selected fix. Require permission from TrustedInstaller to make changes to the file. I was unable to delete the file C:\Windows\System32\drivers\ksthunk.sys.

I decided to delete the offending file using regedit I searched Microsoft, ASUS and Realtek web sites as well as www but I was unable to find any details. On investigation of the driver files it seems that the Realtek installation installed the file C:\Windows\System32\drivers\ksthunk.sys which had no Windows signature. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. Windows cannot verify the digital signature for the drivers required for this device. The Device Drivers properties showed the following It seems that the Windows signature was not valid for files in the Realtek High Definition Audio 64 bit installation software (ASUS link to Global Download 64bit) that was recommended to install. Using the Device Manager - Realtek High Definition Audio.ĭevice Manager has a yellow exclamation mark against 'Realtek High Definition Audio' under Sound, video and game controllers. Windows 10 Pro 64bit Driver Signature Enforcement is ON, forcing non-signed files to be rejected and the device driver not installed. 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. I refreshed and reset Windows 10, but the issue still persists. 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. The requested operation was unsuccessful. Device Manager has an yellow exclamation mark against 'High Definition Audio Controller' under 'System devices', where the error is: I looked at the list of Playback Devices and the Realtek device was missing from there. Audio playback was present until today evening, when the sound from the speakers stopped. Yesterday, I updated the bios and installed a new version of the Realtek audio driver that was there on the Asus website. I have an Asus Maximus VIII Ranger motherboard running Windows 10 Pro.
