HLK test case fail //DF - PNP Rebalance Fail Restart Device Test (Development and Integration)
HLK Test case : "DF - PNP Rebalance Fail Restart Device Test (Development and Integration)" is getting failed with the error WDTF_PNP : ERROR : PNP.RestartDevice() Win32=1 - Incorrect function. We are performing this test on Windows server 2016 VM without any other test software. (We are not installing our driver or software). The test case is falling all the times on clean VMs. I could see the similar test failing with same error in Regression test case. (DF - PNP Rebalance Fail Restart Device Test (Regression)). After applying the latest filter, Regression test is getting passed but Development and Integration test is still failing. Does anyone see this issue and How can I proceed further.SysVAD Virtual Audio Driver Sample updated
