To view the Global Audio settings, click the Audio root folder in the Scene browser.
The Global Audio settings display the Playback Delay setting. See Playback Delay setting for more information.
Use the Playback Delay setting to delay the audio clip playback in your scene in order to sync the sound to your animation. Sometimes a delay is necessary if the processing speed of the animation creates sound synchronization problems.
