Hi Neetu,
in the doc of KSEVENT_PINCAPS_FORMATCHANGE it says that
GenerateEventList is a method of IPortEvents.
I don't know any other way than using the port /miniport driver model.

Hi Uwe,
I am also trying to implement the dynamic format changes support but I
am trying to implement that in streaming minidriver model. I have a
question - what is the GenerateEventList equivalent for minidriver. I
am using StreamClassDeviceNotification. Do you know if it works?
Thanks, Neetu.

Hi all,
I am trying to implement the dynamic format changes support in
Win7, but I'm facing an issue:
If I change the samplerate by calling GenerateEventList, the
format list within the windows control panel is updated.
But it happens from time to time (not allways) that the old format
that was selected before I changed the samplerate is still
available and still selected.
If I play a sound, the new samplerate is used though. So it seems
to me that this a display bug within the windows control panel.
Any ideas?
thanks,
/Uwe
