On the page that contains the audio or video recording that you want to play back, do the following:
Click the icon next to the notes to see or hear the portion of the recording that is associated with those notes.
Stop or pause the playback at any time by clicking Stop or Pause on the Audio and Video Recording toolbar.
By default, the See Playback button on the Audio and Video Recording toolbar is active. This causes OneNote to select in turn each item you created during the recording. If you want to listen without following along in your notes, click the See Playback button to deactivate it.
To play back only the audio portion of a video recording, on the Audio and Video Recording toolbar, click Hide Video Window .
