The best way to make a 
Web page announce itself with sound is still to add an EMBED element, which works on nearly all browsers. 

Put this code in the beginning, middle, or end of your page's BODY region, depending on how much you want 
the reader to see before the browser starts loading the audio file: 

<p>

<EMBED src="comic2.wav" type="audio/wav" hidden=true autostart=true loop=false width=1 height=1> </EMBED>

<p>

The autostart, width, and height attributes are there for Internet Explorer 3.0, to keep it from displaying the Windows 
Media Player and waiting for someone to press the Play button. The loop=false is your insurance against the sound 
repeating, although usually it won't even if you indicate loop=true. The type attribute gives the MIME-type of the 
audio file, which helps the browser figure out how to play it. Most browsers can play embedded WAV, MIDI, AU, 
and AIFF files with the MIME types audio/wav, audio/midi, audio/basic, and audio/aiff.

An example of the code is in the html coding of this page. (sound file is comic2.wav)
