Offhand I'm guessing your device doesn't report correct values for
KSPROPERTY_PIN_GLOBALCINSTANCES, or doesn't support this property at all.
You can tell by running KSStudio. Instantiate the filter and look at the
"Pin Factories"->"Instance Data" node in the "Instantiated Objects"
treeview. mmsys.cpl opens up a stream on each capture endpoint to do the
meters, so when you navigate to the "Advanced" page, the global instance
count should be PossibleCount=1, CurrentCount=1. The "Advanced" page makes
calls to code in audiosrv that relies on these values being correct.

Subject: [wdmaudiodev] AVStream driver in Vista
Hi,
I'm trying to do an avstream audio driver in Vista and is having some
problems getting the advanced tab of the recording endpoint to show. I'm
trying to expose the advanced tab of the recording endpoint to allow user to
select the desired data format, but the advanced tab does not show unless I
allow multiple recording pins to be created. Is there any other way to get
the advanced tab to show other than supporting multiple recording pin
instances? Thanks
KS
