[wdmaudiodev] AVStream and Wave Devices Failure Resolution!

Hi,
I have finally found out why SysAudio is returning
STATUS_NOT_SUPPORTED and failing to create a wave
device.
SysAudio wants to register using
IoRegisterPlugPlayNotification() to get notificaiton
about device arrival/removal. Eventually this request
goes to the underlying bus driver (under my device).
That bus driver (which is relatively new) is returning
STATUS_NOT_SUPPORTED which finally goes back to
SysAudio.
So, I either have to intercept the IRP making the
request and hack a temporary fix, or I have to wait
for the bus driver to be fixed.
All of this information comes from Richard Fricks at
MSFT. I really appreciate everybody's attempt to help
me.
Now, the only remaining question is...What do I do
with all these monkeys?

Yes, if you see the names in KS Studio then you
have the friendly namesOK. Let me know how it goes
adding the mediums & interfaces.

Hi, Matt,Well, I just tried what I think are friendly
names and there is nodifference.Are those the friendly
names? I GUIDs for in the INF file and they appear
asPin Name on the Pins.-----Original Message-----From:

[wdmaudiodev] Re: AVStream and Wave DevicesHi,
Matt,Isn't the friendly name this:
g_PINNAME_AUDIO_RENDER org_PINNAME_AUDIO_CAPTURE?It is
commented out in the example I sent you...but, that is
what I hadorinally...at some point in my testing I
decided to go with those othernames...probably because
they were in some other PortCls driver I
hadwritten.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.-----Original Message-----From:

[wdmaudiodev] Re: AVStream and Wave DevicesThe 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.MattSam Tertzakian wrote:
Hi, Matt,Thank you for your time...Yes, I have tried
several variations of the "needs" and "include"....I
justsent you one of the combinations. I am sure that
is not the problem. Thereis no doubt that SysAudio
sees my device...it is trying to register it,
butreturns STATUS_NOT_SUPPORTED.As for the GUID, yes,
I have tried several variations of that. In my
latestversion, I use "Wave" and "Topology" instead of
a GUID and I useKsCreateFilter 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 reduceclutter
and eliminate some word-wrapping issues.I have not
included my Topology filter since I am pretty that is
not theproblem. If the problem is not here, then I'll
send it separately.constGUIDCaptureFilterCategories

[wdmaudiodev] Re: AVStream and Wave DevicesHere'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.infNeeds=KS.RegistrationNeeds=WDMAUDIO.RegistrationAlsoInstall=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******************WDMAUDIODEV
