Using a hotspot for both sound and moving to another page

I would like to have a hotspot make a sound and then, when the sound finishes, move on to another page (specifically make the sound of a key turning and door opening - yes, for an escape room!). I can do one or the other but not both. Is there a way to do this? Thanks for any help.

Useful answer to this from Ron in Developers section if you are interested.
