Notes
• Alternate content should be placed inside of the
audio
element for browsers that do
not support it.
• Having the correct MIME types on hosted media files is key for playback. You
should also make sure the media types used work in the browsers targeted, because
currently this varies even when the
audio
element is supported.
• Flash will often be used to avoid cross-browser audio concerns. Until this element is
widely supported, developers are advised to continue to use Flash or to rely on
elements like
bgsound
.
