You can enumerate KSCATEGORY_AUDIO driver interfaces. These are the filter

For each filter factory, you can instantiate it, and then enumerate supported
property sets.

For each property in each supported property set, you can issue “basic support”
requests on your filter.

For pin properties, you would need to instantiate a pin first.

Subject: [wdmaudiodev] Setting miniport KS properties from a service

I need to call into the KS properties exposed by miniport driver from a user
mode service. ie. instead of calls from portclass.
Is there a way that the service can discover these properties for each pin and
call as and when required.
