Can I skip some test in HLK for a virtual audio driver?

NTDEV

Hi, I created a virtual micphone device based on one of Microsoft’s audio driver sample
Now I need to submit the driver for sign, and I learned that I need to first pass the HLK test
I then ran the HLK test and there were 50 failed test cases, for example: > Failed DF - PNP Remove Device Test (Development and Integration)
Then I start to check how to fix these issues, then I learned that I need to prepare the test env like below

So here my question is: what I am build is a virtual mic device, do I need to pass all the tests?

Thanks in advance

Whether or not you really need the HLK testing, you should DEFINITELY be able to pass all of the PNP tests. That failure indicates a problem.

If you submit for attestation signing, you don’t need any extra equipment.

And of course if you use attestation signing you are restricted to w10
generation systems.

Thanks very much for your help

So from my understanding for win10 I can use attestation signing for driver and no need to pass HLK test, right?

And for sure I will check the hlk test result and make sure some of them(which suitiable for my virtual driver)
will be passed

Yes, if you don’t care about anything before Windows 10, then attestation signing will work fine.
