I have welcome.html file in that i have one audio tag inside that source attribute i am adding link from the jio-saavan but it's not playing when the webpage is opened but in console i am getting following error..
Error on console
welcome.html:28 Uncaught (in promise) DOMException: play() failed because the user didn't interact with the document first.
<audio autoplay id="my_audio">
<source src="https://docs.google.com/uc?export=download&id=11wfYWiukbIZJQnDL385jQs2SGQA5ESbL" type="audio/mpeg">
</audio>
<script>
document.getElementById('my_audio').play();
</script>
The error is telling you clearly that you can't start an audio (or even a video if not muted) if the user haven't interacted with the page before.
Some links to better help you understand the policy on autoplay:
