Stay Updated with Browser Changes

Browsers and their autoplay policies might change over time. Keep yourself updated on the most recent developments and modifications concerning autoplay functionality. Regularly check browser documentation and developer forums for updates that might affect your HTML audio autoplay implementation.

Step-by-Step Guide

Following are the steps you may follow when HTML audio autoplay is not working:

  • To play audio in autoplay mode or hidden, you can use the <iframe> tag. However, you can use a workaround if encountering issues making the audio tag runnable. You can achieve this by playing a short audio file named “silence.mp3” using the <iframe> tag. The <iframe> element can be hidden by applying the CSS display: none property or by using the hidden attribute.
  • This approach will successfully set your audio tag to autoplay. The “silence.mp3” file is typically very short, about 0.5 to 1 second in duration, so that it won’t interfere with your main audio content. After playing this “silence.mp3” file, you can run any other audio file you want to autoplay.
  • Below is a code snippet demonstrating the usage of the <iframe> tag to play a short audio file in autoplay mode:
<iframe src="silence.mp3" hidden></iframe>
  • After the <iframe> section, you can create a <audio> tag with the autoplay attribute. Within this tag, you specify the audio file’s source by using the <source> element and linking to the audio file you want to play.

For instance, the code snippet below demonstrates how to enable autoplay mode for playing an audio file named “my_audio.mp3”: “my_audio.mp3” in autoplay mode:

<audio autoplay>
<source src="my_audio.mp3" type="audio/mpeg">
  • Finally, you close the <body> and <html> tags with their corresponding closing tags: </body> and </html>, respectively.
