Hi David,
Thanks for your reply.
The datarange used is basically:
KSDATARANGE PinDataRange =
{
sizeof(KSDATARANGE),
0,
0,
0,
STATICGUIDOF(KSDATAFORMAT_TYPE_AUDIO),
STATICGUIDOF(KSDATAFORMAT_SUBTYPE_PCM),
STATICGUIDOF(KSDATAFORMAT_SPECIFIER_NONE)
};
In the DataRangeIntersection handler the subtype is KSDATAFORMAT_SUBTYPE_PCM
and the formatTag WAVE_FORMAT_EXTENSIBLE
Is this not sufficient?
Ed

Ed,
I’m no expert on either issue, but I’m guessing the problem is not with the INF
file.
Check the following places for support of Dolby, DTS…
GetDescription PPCFILTER_DESCRIPTOR table. If the DataRanges in
the PCPIN_DESCRIPTOR points to a entry with
KSDATAFORMAT_SUBTYPE_DOLBY_AC3_SPDIF, that will show Dolby. (I suspect this is
the issue in your case)
DataRangeIntersection handler.
KSPROPERTY_PIN_PROPOSEDATAFORMAT property handler.
The end point names might be coming from the KSPROPERTY_GENERAL_COMPONENTID
property handler. Although the actual text comes from the INF file, the text
that shows for each endpoint comes from the property handler. Specifically the
GUID in PKSCOMPONENTID Name element.
Hopefully this helps.
Thank you,
David A. Hoatson

Subject: [wdmaudiodev] Inf file problems.
Hello,
I wonder if anyone can help me with two problems with the inf file for our
audio driver.
The inf file was created using the MSVAD driver's inf file as a template.
The first problem is more of a question. In the Sound System Control Panel, the
tab for "Supported Formats" (Dolby, DTS etc.) is always shown. Is this
something that can be removed by changing the inf file or should I be doing
something more fundamental?
The second problem is that since the 1903 update to windows 10, the device
endpoint names are not being created in the registry, so all channels show up
as "Digital Input" or "Digital Output" in the Sound Control Panel. I've been
staring at the inf file till I'm blue in the face, but I just can't see why the
entries are no longer written to the registry.
Can anybody help by looking at the inf file below?
Best wishes
Ed Tottenham
