autoplay is a boolean attribute. autoplay="false" actually means that the value of autoplay is true. So the audio plays. From the HTML 5 spec: "The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value. "

Ever confirmed: true
"The autoplay attribute is a boolean attribute." (§188.8.131.52) "The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value." (§2.4.2) Therefore, autoplay="false" is actually setting the attribute to true. To set it to false, don't specify autoplay at all. RESO INVA
