Definition and Usage

The autoplay attribute is a boolean attribute.

When present, the audio will automatically start playing as soon as it can do so without stopping.

Note: Chromium browsers do not allow autoplay in most cases. However, muted autoplay is always allowed.

Add muted after autoplay to let your audio file start playing automatically (but muted).

The numbers in the table specify the first browser version that fully supports the attribute.
