That is correct. Setting the default driver via the INF is no longer supported
in Windows 7. The Windows 7 device selection heuristics are now used to select
the default device. The user can still override this selection via the control
panel. Removal of support for this INF entry was necessary to enable our new
stream routing scenarios. For example, audio will automatically route to your
headphones when you plug them in.

A driver can request in its .inf that it be made the default audio device at
install time:
http://msdn.microsoft.com/en-us/library/bb981547.aspx
AddReg = XYZ-Audio-Device.AddReg
...
[XYZ-Audio-Device.AddReg]
HKR,,SetupPreferredAudioDevices,3,01,00,00,00
For the RDP scenario it may be reasonable (or not) to disable all of the other
audio drivers via SetupAPI calls.

I have created an audio device driver, during the RPD session, login time i
have to set that driver as default audio driver for streaming the audio data to
my RDP client.

May I ask again, why do you need to? We’d like to understand the scenarios in
case there are other improvements we should make in this area the future.

Thanks guys,
I figured it out how to do this. writing to the registry from vc++
will do the work.
