Hi, Matt,

Well, I just tried what I think are friendly names and there is no
difference.

Are those the friendly names? I GUIDs for in the INF file and they appear as
Pin Name on the Pins.

Hi, Matt,

Isn't the friendly name this: g_PINNAME_AUDIO_RENDER or
g_PINNAME_AUDIO_CAPTURE?

It is commented out in the example I sent you...but, that is what I had
orinally...at some point in my testing I decided to go with those other
names...probably because they were in some other PortCls driver I had
written.

But, I will try those again, right now...just to make sure...

Or, if those are not the "friendly names"...then maybe I don't know what a
"friendly name" is.

The first thing I notice is that you don't have any friendly names for 
your pins - the Name member of KSPIN_DESCRIPTOR.  This may actually be 
all it takes.  Try adding that - if that doesn't work, I'll do a closer 
look.

Windows Vista will use the friendly names of the pins to name the wave 
devices, so you'll want to do this anyhow.

Hi, Matt,

Thank you for your time...

Yes, I have tried several variations of the "needs" and "include"....I just
sent you one of the combinations. I am sure that is not the problem. There
is no doubt that SysAudio sees my device...it is trying to register it, but
returns STATUS_NOT_SUPPORTED.

As for the GUID, yes, I have tried several variations of that. In my latest
version, I use "Wave" and "Topology" instead of a GUID and I use
KsCreateFilter twice and pass in "Wave" and "Topology".

Again, I just sent one of the variations. 

I thought that perhaps it was because I did not have a Topology filter. So,
created that...as a bonus, I get two STATUS_NOT_SUPPORTED, once for the
    

Wave
  

and now for the Topology.

Here is some of the stuff you asked for...I have removed comments to reduce
clutter and eliminate some word-wrapping issues.

I have not included my Topology filter since I am pretty that is not the
problem. If the problem is not here, then I'll send it separately.

Here's what I have in my INF that's different:

My "include" and "needs" lines are different; here's mine:

Include= ks.inf, ksfilter.inf, wdmaudio.inf
Needs=KS.Registration
Needs=WDMAUDIO.Registration
AlsoInstall=ks.registration(ks.inf),wdmaudio.registration(wdmaudio.inf)

You've got this:

XXX_FILTER_REF_GUID     = "XXXX0"

but it's a real GUID in your actual INF file, right?  And you're passing 
that same GUID in your filter descriptor as the reference guid?

What you have here looks OK, though.  I would guess that the problem is 
with your filter descriptor.  If you like, go ahead and post the whole 
thing (filter, pins, nodes, connections, everything).

Matt
