Hello, I am working on a audio driver which is based on wavecyclic. My driver is failing Wave test with following errors, 1) FAIL : Data Intersection Test\Render Streaming\Check Supported Formats CKsPin::Instantiate. Failed to instantiate KSPIN_DATAFLOW_IN pin! KsCreatePin returned = 0x00000001 [ GetLastError() returned 1 (0x1) - Incorrect function. ]. FAIL: KSPROPERTY_PIN_DATAINTERSECTION Succeeded, Pin Creation Failed. 2) Compliance Tests\UAA-Compliance Test 1.FAIL: The Device driver is not one of the UAA Compliant types (HDAudio,USB Audio 1.0, USB Audio 2.0, Bluetooth)! Regarding first failure, i tried to search about that but failed to understand what exactly Failure is and reason behind the failure. My primary understanding says, this failure is because my driver is not supporting KSPROPERTY_PIN_DATAINTERSECTION property. Is this right ? Can anyone please help me here ? Regarding second failure, as my driver is virtual driver, how can i pass this failure ? Should my driver must be from one of the category listed in failure ? Thank you.
