we send a KSEVENT_PINCAPS_FORMATCHANGE event
Did you confirm this event is actually getting raised - by using tracing, or by
setting a breakpoint in your event handler and verifying that it gets hit?
Are you raising it on the streaming pin (the one on the wave filter?)
his suggestion was to implement our own version of
CMiniportWaveRT::DataRangeIntersection
In general you need to write your own DataRangeIntersection implementation if
any of the following conditions are met:
1. You support any formats with nChannels > 2
2. You support any compressed formats
3. You support stereo but not mono

Thank you for your reply Matthew,
Yes, we created them with the same name, and after we have created the new
drivers, we send a KSEVENT_PINCAPS_FORMATCHANGE event.
We have been talking with a Microsoft Support Escalation Engineer, and his
suggestion was to implement our own version of
CMiniportWaveRT::DataRangeIntersection, but we found that DataRangeIntersection
is never called, this was latter confirmed by the support engineer.
Thanks,
Paul
