My question was referring to the previous reply, that you could create a timeline action for audio. My pint was, this is not supported when exporting a hype project intended for iOS.
From the Hype Documentation:
iOS: Audio will not play on iOS devices without user interaction. Thus, audio played ‘On Scene Load’, ‘On Scene Unload’, or using a timeline action will not play back on iPhones, iPads, or iPod touches. Use Mouse Click actions to play audio on iOS. Please see this forum thread for workarounds.
It is disappointing that this still requires workarounds and that there is no way to use timeline actions for Audio intended for iOS.
