Audio Delay

Hi,

I am facing a really strange issue.I have a wordpress website in which I have used html 5 audio tag .Whenever I play audio it delays it takes 2-3 sec to start on Safari. On other browsers it is working fine.I have done lot's of research and tried many things JS scripts but nothing worked.Can you please check and let me know any solution for this.
