In Vista, the notification mode (event driven) is used on only in limited 
scenario (AUDCLNT_SHAREMODE_EXCLUSIVE + AUDCLNT_STREAMFLAGS_EVENTCALLBACK).
In Win7, the notification is used in most of the scenarios.

Are you running in Vista?

What audio solution are you using? HD Audio, AC97, or others?



Thanks

Hi,

Our WaveRT driver already has push mode support and is running well in
Vista.
We try add to it pull mode support(IMiniportWaveRTStreamNotification).
We followed the recommendations outlined in the DDK,
http://www.microsoft.com/whdc/device/audio/wavertport.mspx and
Win7ChangesRelatedToAudioDriver.doc.
The problem is: the driver continues to work a mode without notification.
The "old" methods (AllocateAudioBuffer) are called
instead of new ones (AllocateBufferWithNotification).
