Device Driver Code 52 unable to verify digital signature for camera and High Definition Audio

Hi All,

 

I've been struggling for about a month.  Since I reinstalled Windows 10 Home (1067) (on a new SSD) the 100-15IBY Camera and High Definition Audio Driver has failed with Code 52 unable to verify digital signature.

 

Windows cannot verify the digital signature for the drivers required for this device. 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. (Code 52)

 

I've tried everything... permissions on files, bcedit command lines, downloading newer drivers from Realtek, reinstalling windows again with Legacy and then UEFI modes... disabling Secure Boot, reinstalling again with Secure Boot in "Setup - Disabled" mode...

 

The only way to get the audio and camera to operate is to reboot in safe mode and disable the Driver Signature Enforcement - that only works for a single boot.  So I know the drivers are correct and the devices work... it's a trust issue with the drivers.

 

The High Definition Audio one is specifically a Microsoft Driver... why wouldn't that be trusted!?

 

Please anyone?  It must be a common problem - has anyone solved it?

Thanks for replying Krakken,

 

That's the method I've tried a few times with and without 'secure boot' enabled and it doesn't work in Windows 10 1607.


Solution 1 works for a single reboot (ie using advanced safemode option to disable driver signing enforcement), but that only proves the devices and drivers works, it's not persistent.

 

I went through the whole thing again to prove it and I still have Code 52 as described above after running 

  • bcdedit /set testsigning on (rebooting)
  • bcdedit /set nointegritychecks ON (rebooting)

 

Has anyone else here reading this actually done a clean install of Windows 10 on their 100-15iby and got their soundcard working?

 

This is the only reason I can think this is failing - https://blogs.msdn.microsoft.com/windows_hardware_certification/2016/07/26/driver-signing-changes-in...
