Using audio play via callback

I am using html.Audio and would like to find a way to trigger “play” from a callback, I can only do it from the control as of now. This has consumed a lot of my time, please help. Thank you.

I think my question’s sample code can help.

Still it is not good for iOS safari and I am looking for better solution.
