Those audio drivers that uses porcls will have the following lines in
its INF.

Include=3Dks.inf, wdmaudio.inf

Inside wdmaudio.inf, you will find several registries that have
rundll32.exe in it.

I think that would answer your question.

Subject: [wdmaudiodev] .inf confusion


Hi.  I'm writing an Avstream-based, 1394 audio driver.  In  the DDK, I
see lots of examples of the necessary .inf directives to install a
portcls based audio driver.  The Gfx DDK sample is Avstream-based and I
have studied it and have some questions:

- In a portcls the entries,

HKR,,AssociatedFilters,,"wdmaud,swmidi,redbook"
  HKR,,Driver,,xyzaud.sys=20
  HKR,Drivers,SubClasses,,"wave,midi,mixer,aux"

... and the interfaces.setion describe and expose the driver's filters /
interfaces.

In the Avstream samples .addregs, I see one or more "rundll32.exe
streamci,StreamingDeviceSetup..." Runonce directives. =20

Which, if any, portcls-based audio driver .inf directives does this
replace?

What are the standard .inf directives for an Avstream-based,
Audio-in/out Midi-in/out driver?

Any help appreciated.
