The port class driver responds to this property on your behalf, based on
the information you provide.  In this case, the test is trying to
establish a connection with an invalid number of channels, and you
approved the request.  Are you actually validating the format in
IMiniPort::DataRangeIntersection and IMiniportWaveCyclic::NewStream, or
are you just approving everything?

An audio driver is supposed to allow data to be written to it even while
it is in the PAUSE state.  This error says that you are not doing that.
