Hello Dennis, > i want to get PID of the application which is accessing my audio > driver in VISTA, what is the correct way of getting it. There is no correct way. Most applications don't interact with a driver directly, they interact with intermediate layers (for example, AudioDG service in Vista). In general, a driver receives no information about applications that use audio features.
