Do you return STATUS_PENDING or STATUS_SUCCESS from your Process callback?
I tried both, and it made no difference.
Has the graph changes to KSSTATE_RUN?
Yes.
Do you set KSPIN_FLAG_PROCESS_IN_RUN_STATE_ONLY?
Yes.

You just need to return and wait until your Process callback gets tickled
The problem is I *always* get NULL. Actually, if I don't specify
KSPIN_FLAG_ASYNCHRONOUS_PROCESSING in the pin descriptor, the Process callback
is called over and over again from ks!CKsQueue::SetDeviceState.
Do you return STATUS_PENDING or STATUS_SUCCESS from your Process callback? Has
the graph changes to KSSTATE_RUN, or are you still in KSSTATE_PAUSE? Do you
set KSPIN_FLAG_PROCESS_IN_RUN_STATE_ONLY?
