IAudioVolumeDuckNotification::OnVolumeUnduckNotification method (audiopolicy.h)
The OnVolumeUnduckNotification method sends a notification about a pending system unducking event. For more information, see Implementation Considerations for Ducking Notifications.
Syntax
HRESULT OnVolumeUnduckNotification(
[in] LPCWSTR sessionID
);
Parameters
[in] sessionID
A string containing the session instance identifier of the terminating communications session that initiated the ducking. To get the session instance identifier, call IAudioSessionControl2::GetSessionInstanceIdentifier.
Return value
If the method succeeds, it returns S_OK.
Remarks
After the application registers its implementation of the IAudioVolumeDuckNotification interface by calling IAudioSessionManager2::RegisterDuckNotification, the session manager calls OnVolumeUnduckNotification when it wants to send a notification about when ducking ends. The application receives the event notifications in the form of callbacks.
