Can any one please answer these questions w.r.t Terminal server audio
operations in VISTA.
1. will audio engine has only one instance per system or it is instantiated
in each terminal server session (i.e, output of audio engine to Device
driver is mixed output of all session stream or individual session stream)
2. If i get a audio stream in my driver is their a way that i can decide
that stream is from session with id X.
