Audioengineendpoint.idl will be in the final SDK for Windows 7. However, I
believe there should hardly ever be a need to use the AE_CURRENT_POSITION
structure, though, since it is related to Terminal Server. Do you mind saying
why you need this?
There are some minor audio header corrections between Beta and final release.
So if you are trying to get this definition just to make your code build but
are not actually using this structure, then hopefully your problem will go away
when you move to the final SDK.

Thanks Matthew,
I wonder why I can not find audioengineendpoint.idl file.
I did find the audioengineendpoint.h file which has the definition,
But I was looking for the .idl file.
I have both SDK and DDK installed for windows 7, but strangly i don't
find the file.
could you please help me in locating the file.
The SDK installed is "Microsoft Windows SDK for Windows 7 (7000.0.4011)
The DDK installed is "Microsoft Windows Driver Kit 7.0.7000.1"
