Yes, pin instantiations are only attempted on the wave filter. The topology
filter typically does not have any pin factories that support meaningful pin
instantiation.
When the test case fails, are you seeing a NewStream() call?
What formats do you support?

Hi Tim,
As you said, i tried instantiating my driver with ksstudio. I selected my wave
filter from KS Studio and successfully instantiated pin on wave filter.
Is failure which i mentioned is related to wave filter only ?
Also i am getting one more failure in same test case mentioned above saying:
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
FAIL: Pin does not support WLP required sample frequencies of:
- 44100 Hz
- or 48000 Hz
But my driver supports above mentioned sample frequencies, still i don't
understand why this failure ?
Thanks.

Hi Tim,
No, i haven't tried using ksstudio to instantiate my driver. To be frank, i am
not aware of this. What exactly will happen when i instantiate driver with
ksstudio and how to do that ( if possible just give me some reference link or
document ) ?
Thanks.

No. Read the error: KSPROPERTY_PIN_DATAINTERSECTION succeeded. Pin
creation failed. You're going to need to put some debug prints into
your driver to chase down which function is failing. Have you tried
using ksstudio to instantiate your driver? Does it work in graphedt?

You can't WHQL a virtual audio driver.
