One of my problems seems to be related to handling of
KSPROPERTY_PIN_PROPOSEDATAFORMAT, whenever it is called, I never get back the
requested buffer size, i.e. when returning STATUS_BUFFER_OVERFLOW I set
PropertyRequest->ValueSize to sizeof(KSDATAFORMAT_WAVEFORMATEX) which is 82
bytes (per msvad example code), however, I only get back 64 bytes (in
PropertyRequest->ValueSize) after that call (??)
So my main problem I think is that KSPROPERTY_TYPE_SET or KSPROPERTY_TYPE_GET
handler never gets called due to the problem above.

To answer your original question, you cannot put a wildcard in thefor you.
.inf, but you can dynamically add KSCATEGORY_AUDIO interfaces by
calling IoRegisterDeviceInterface. Since you’re a portcls miniport you
will want to use PcRegisterSubdevice which does some of the dirty work
I do use PcRegisterSubdevice (in InstallSubdevice, as from the msvad
example), but using the "Wave_XXXX" name fails to give me any audio
device in control panel, is there anything else I need to do ?
There appears to be no sample for KSEVENT_PINCAPS_FORMATCHANGE.It is
important to note that KSEVENT_PINCAPS_JACKINFOCHANGE is raised onthe
pin factory that sits on the hardware end of the signal path (the oneshould be
with the jack descriptions) but KSEVENT_PINCAPS_FORMATCHANGE
raised on the pin factory that sits on the software end of the signal
path (the one where KsCreatePin gets called.)
Ok, the PPORTEVENTS interface pointer is queried in
CMiniportWaveCyclicMSVAD::Init, so I hope that is the correct place to do it ?
Can you also file a problem report for the lack of a sample and share
that as a direct link?
I did, however, I missed the "copy link" feature. Sorry 😊

Hi Matthew,
Then I probably am using it incorrectly. Are there any example sources
using KSEVENTSETID_PinCapsChange/
sysvad example uses only KSEVENT_PINCAPS_JACKINFOCHANGE.https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fblogs.

KSEVENTSETID_PinCapsChange should work. If it doesn't, please file a
problem report in the Feedback Hub and share a direct link.

Subject: [wdmaudiodev] FW: VAD woes on Win 10
Hi all,
I'm trying to get my VAD to work on Win 10, it is based on the old
msvad WaveCyclic example (using Portcls).
In essence the problem is that the device, named "Wave", can change
its capabilities (#channels, samplerates aso) through a control
interface. But with the new and fancy caching of capabilities in
Windows 10 (which I have no clue what the use is for), whenever I
change the caps from the first registered caps, Sound control panel
will not display the "Advanced" tab for the device (where samplerates
b.com%2Feiz%2FSynchronousAudioRouter%2Fblob%2Fmaster%2FSynchron(https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgith
One way to tell Windows that the caps has changed, is through the
KSEVENTSETID_PinCapsChange event. I post this whenever I bring up
the device, but alas, Windows does not seem to requery the
capabilities. There seems to be a bug in this mechanism acc. to
these sources

So, the workaround seems to be to change the "Wave" name whenever
caps change. So, I thought I'd make a naming scheme "Wave_XXXX"I
where XXXX is a hash combination of #channels + all supported
samplerates. But if
do this, Sound control panel doesn't show my device at all, probablybecause
the "Wave" name that is also specified in the .inf file:
[Strings]
...
KSNAME_Wave="Wave"
KSNAME_Topology="Topology"
[DevInst.<arch>.Interfaces]
AddInterface=%KSCATEGORY_AUDIO%,%KSNAME_Wave%,DevInst.I.Wavepology
https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.request@xxxxxxxxxxxxx?subject=subscribe <mailto:wdmaudiodev-
is not matched in the driver. So, the question is, how do I
programmatically do an "AddInterface" with the "Wave_XXXX" name so
it can popup in the Sound control panel ? Or is it possible to have
AddInterface in the .inf file with a wildcard ?
Regards
/Robert
