Adjusting audio volume for all slides?

Hi boonedogr and welcome to our community

In the words of Yoda: Hmmm, seems a bug we have found!

So here is how to make it stick.

1. Click Audio > Edit timing... and you should see the "Edit Audio Timing" dialog.
2. Click the Insert Silence toolbar button. This should produce the "Insert Silence" dialog.
3. Change the "Insert" field so it reflects 0.001seconds of silence.
This step is necessary to trick Captivate into accepting the audio has indeed changed. I use 0.001 seconds as it is the minimum you can insert and it should have absolutely no discernable effect on your movie.
4. Now click the Adjust Volume button to see the "Adjust Volume" dialog where you can alter the volume level as well as boost dynamics and whatnot.
5. Make adjustments as desired.
6. Click OK to dismiss the Adjust Volume dialog.
7. Click OK to dismiss the Edit Audio Timing dialog
At this point, you should notice several progress indicators as the audio clips for all slides with audio are adjusted to reflect your new settings.

*NOTE: This will have no effect on Background Audio or Object Level Audio. Those clips will need to be adjusted manually as a separate process.

Hope this helps a bit... Rick
