When I record Captivate automatically increases my volume to level 100

Hi,

I am making a Powerpoint presentation where I need to record an audio for each slide. Every time I press record, Captivate increase my volume to level 100 automatically. At the moment I record and readjust the level whilst recording and then use editting tools in Captivate to cut the 'reajdusting process'. However, this is taking too much time and is very tedious. I know others have had this problem before. Is there no way to fix this?

By the way I have done everything from the Windows side of things like unchekcing the "allow applications to take exclusive control of this device".
