How to keep audio playback in "automatic" mode for ALL slides?

While you can't set that as a default, you can insert all the audio files, then run this macro. It doesn't remove the original click animation, but it adds an autoplay animation before the click:

Sub AutoPlayAudio()

    Dim oSlide As Slide

    Dim oShape As Shape

    Dim oEffect As Effect

    For Each oSlide In ActivePresentation.Slides

        For Each oShape In oSlide.Shapes

            If oShape.Type = msoMedia Then

                If oShape.MediaType = ppMediaTypeSound Then

                    Set oEffect = oSlide.TimeLine.MainSequence.AddEffect(oShape, msoAnimEffectMediaPlay, , msoAnimTriggerWithPrevious)

                    oEffect.MoveTo 1

                End If

            End If

        Next oShape

    Next oSlide

End Sub

Hi,ReadVaughan. My name is Hilla. I am an independent advisor, Thanks for being part of the Microsoft Community, I will to help you.

The auto-automatic option is to play automatically when you advance to the slide on which the audio file is. PowerPoint doesn't record audio or video during transitions between slides, so don't speak while advancing the slide. Also, include a brief buffer of silence at the beginning and the end of each slide to make the transitions smooth and ensure that you don't cut off audible narration while transitioning from one slide to the next.

I hope this helps, but please let me know if you need anything else.

You can't set that as a default, sorry. If you need help implementing the macro, please post again.

Hillary,

Thanks for taking the time to try and help.  I had looked at and used the info on the link you sent.

I can successfully create an audio file for a slide, insert it and then by clicking on the sound icon I can go to Audio playback and under the "start" dropdown - I select "automatically" and this works for this one slide. But I have to do that same time consuming maneuver for each individual slide  which is way more work than I want on a 60 slide PPT.

When I go to Audio Playback the "Start" dropdown shows 3 options:

-   "in click sequence"  (which is what it defaults to)

-   "automatically"

-   "when clicked on"

I can't find a way to make "automatically" the default for all the slides or have it apply to all the slides so that I don't have to set the "playback" for every single slide.
