    <p>I am working on a PowerPoint 2007 VSTO add-in, and I am running in a small issue. The add-in adds sounds to the current slide using the following code:</p> <pre><code>var shape = slide.Shapes.AddMediaObject(soundFileLocation, 50, 50, 20, 20); </code></pre> <p>The resulting shape does have a sound, and can be played through the PowerPoint slide. My problem is that, given a reference to a shape that has been created that way, I would like to programmatically play the sound, but I can't find the way to do it. I tried</p> <pre><code>var soundEffect = shape.AnimationSettings.SoundEffect; soundEffect.Play(); </code></pre> <p>but this fails/crashes, and when I check soundEffect, its type is ppSoundNone.<br> <strong>Edit:</strong> got some partial success with</p> <pre><code>var shape = slide.Shapes.AddMediaObject(fileLocation, 50, 50, 20, 20); shape.AnimationSettings.SoundEffect.ImportFromFile(fileLocation); </code></pre> <p>Doing this allows me to play the sound with:</p> <pre><code>var animationSettings = shape.AnimationSettings; var soundEffect = shape.AnimationSettings.SoundEffect; soundEffect.Play(); </code></pre> <p>However there is one major issue; this works only for the last shape added. For some reason, shape.AnimationSettings.SoundEffect.ImportFromFile(fileLocation) seems to reset the SoundEffect property to ppSoundNone for the shapes previously created... </p> <p>I would be surprised if this wasn't feasible, but I can't seem to find how - any help would be much appreciated!</p>
