Answer 1

I've set the "autoplay" parameter to "true", so the sound will start playing as soon as the page loads:

Example
<object data="horse.wav">
<param name="autoplay" value="true">
</object>

The <param> tag is used to define parameters for plugins embedded with an <object> element.

Tip: HTML 5 also includes two new elements for playing audio or video: The <audio> and <video> tags.
