Hello,

Can an AVstream driver create an Audio only filter via a filter factory 
(perhaps in addition to video filters) that are seen as part of mf / mmapi / 
wasapi?

Must I use a portcls driver to do this?

I have tried using different KSTOPOLOGY_CONNECTION structures, does an example 
exist?

Thank you in advance.
Regards,
