Thank You sir for helping me out,
All voulme controls are working fine. I got the attestation signing for the driver and it is getting installed in few win10 x64 laptops and working properly. But in few systems, even it is installed, virtual audio driver is not visible in Volume control.
My Virtual Driver name is ClearVoiceMvns
In device manager the under** sound&Volume&cgame controller** . It is in yellow mark. And in details of the driver, it is error number 52. And it is not able to recognize the 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)
As I searched in net, it is because of windows software updates. After disabling secure boot, it is working properly.
Can you suggest me any way, so that it can able to recognize the digital sign without disabling the secure boot?
Advance Thanks
