I am evaluating latest Lead tool for my applications processing needs...I want to get the Audio Volume processer's Amplitude settings programatically from my c#.net code. I tried diff way but it always leads me to some COM casting exceptions.

Can you please guide me , how I can alter that amplitude setting of Audio Volume filter from my c#.net  code.
 LMAVolumeLib.LMAVolumeClass objVol = objConvertorControl.GetSubObject((int)(LTMMLib.ltmmConvert_Object.ltmmConvert_Object_SelAudioProcessor));

If you try to declare the LMAVolumeClass as follows, do you get the same error?
LMAVolumeLib.LMAVolumeClass objVol = (LMAVolumeLib.LMAVolumeClass)axltmmPlay.GetSubObject((int)LTMMLib.ltmmPlay_Object.ltmmPlay_Object_SelAudioProcessor);
