Very likely a test bug, then.

Could be. Does it repro on the MSVad WaveCyclic driver?

Hello,
I am working on a virtual audio driver.This driver is based on wavecyclic port
driver. I am trying to pass General audio test for the same driver but i am
getting failure in test case which i mentioned below,
IOCTL\KS defined\IOCTL_KS_WRITE_STREAM\Cancel IO
KSPIN_DATAFLOW_IN pin is currently in state KSSTATE_STOP; want it to be in
state KSSTATE_PAUSE
Setting KSPIN_DATAFLOW_IN pin to state KSSTATE_ACQUIRE
Setting KSPIN_DATAFLOW_IN pin to state KSSTATE_PAUSE
ERROR: Overlapped Event was NOT signaled within 30 seconds after
DeviceIoControl call.
ERROR: attempt to prime data returned 258 instead of ERROR_IO_PENDING
As per my understanding,this test is trying to write data even if pin is in
pause state and expecting return value ERROR_IO_PENDING. Here i am not able to
understand that how we can take care in miniport driver about handling of
IOCTL_KS_WRITE_STREAM as this request is completely handle by port driver.
I observed that, our driver do get calls to
IMiniportWaveCyclicStream::GetPosition and IDmaChannel::CopyTo function when
test put a pin into pause state.
I am not sure but is this a bug in test only? Please help me.
Thanks.
