Correct, KSStudio hasn't yet been updated to show jack info.  If you search the 
logging window though, it should show

KSStudio does not recognize property GUID 
{4509F757-2D46-4637-8E62-CE7DB944F57B} supported by the filter.
This is not a driver bug.

Mitch

I don't think KSStudio would display it because KSStudio does not know such a 
new KSPROPSETID.
You can verify this by running your HD Audio device with inbox HDAudio driver 
and check information from mmsys.cpl and ksstudio.

I tried that too. Works the same. Should not KsStudio report at least something 
about this new property for the pin?



Thanks,

I would try to replace KSPROPSETID_Audio with KSPROPSETID_Jack in your 
PCPROPERTY_ITEM structure for the topology filter
{
&KSPROPSETID_Jack, //<---------------------------like this line
KSPROPERTY_JACK_DESCRIPTION,
KSPROPERTY_TYPE_GET | KSPROPERTY_TYPE_BASICSUPPORT,
PropertyHandler_Topology
},

Thanks.

Subject: [wdmaudiodev] KSPROPERTY_JACK_DESCRIPTION

I need to display speaker connection status in a portcls audio driver. To
begin I have modified audio/msvad/simple code in the DDK 6000. But the jack
is not displayed on the audio panel and the KsStudio does not show the
KSPROPERTY_JACK_DESCRIPTION when the driver is instantiated. The code is
below.

Any help or code sample would be appreciated.

Thanks,
Nikolay

{
&KSPROPSETID_Audio,
KSPROPERTY_JACK_DESCRIPTION,
KSPROPERTY_TYPE_GET | KSPROPERTY_TYPE_BASICSUPPORT,

&KSPROPSETID_Audio,
KSPROPERTY_AUDIO_CPU_RESOURCES,
KSPROPERTY_TYPE_GET | KSPROPERTY_TYPE_BASICSUPPORT,
PropertyHandler_Topology
