Does your presentation need sound?

The upload and own-computer forms ask whether your presentation needs sound: for example video with sound, music or audio clips. Answer Yes, No or I don't know yet. The answer is saved at once.

If a file has sound (a video with an audio track, or an embedded audio file), Yes is selected already. Check the answer anyway.

The answer shows on the confirmation, in the organiser's status view, in the manifest and in the partner view.
