How do I fade out a sound using matinee?

That’s basically my question. Do I have to use an event track and use blueprint for that?

You can set the volume of a sound cue in Matinee for every keyframe you create for that sound track.

Make sure you select the sound track and dont have a sound cue selected in the content browser before you create a keyframe…

Can you post a screenshot of your Matinee please?

And how do I set up a keyframe? Everytime I do it it just inserts a new sound on top of the previous one.

When I do that it just doesn’t let me create a keyframe

I’ve got the exactly the same problem.
With the sound track selected in counter browser i’m able to insert a keyframe but the song restart from 0.
With sound track selected in matinee (and nothing selected in counter browser) i can’t insert keyframe in matinee…
I just want to create a fade-out of the soundtrack at the end of the matinee timeline.

In UE4.6 I haven’t found a way to do it to an individual sound track but you can fade all the matinee sound out by doing this:

  1. Right-click on your Director Group
    and add an Audio Master track. Add
    two keyframes in the Audio Master
    track to mark the beginning and end
    points of your sound fade.

  2. Right-click on each of these keyframes in the Audio Master track and set
    their volumes (e.g for a fade out
    set the end keyframe to 0 and the
    beginning keyframe to 1). Use the
    same process to set the Interp mode
    of both keyframes to Curves
    (Auto).

  3. To check your fade, open the
    Curves Editor and click on the
    little square on the Audio Master
    track that looks like a graph. After
    centering the curves editor
    viewport, you should see the curve
    showing a fade-out between your two
    keyframes. When you play the Matinee
    you should hear the sound fade.

Same problem here. It just seems not possible to add a key in a sound volume curve.
