Managing Media Player object


i have a php page. in this page i check a value taken from a text file. If the value is bigger than a threshold number, i want to make a sound( an alarm). Now i add an media player object.

<OBJECT ID="WinMedia" width=160 height=120
mplayer/en/,1,52,701" standby=
"Loading Microsoft® Windows® Media Player components..."
<PARAM NAME="AutoStart" Value="False">
<PARAM NAME="FileName" VALUE="_page/alarm_2.wav">
<EMBED type="application/x-mplayer2"
MediaPlayer/" SRC="_page/alarm_2.wav" name="WinMedia"
autostart=0 width=160 height=120 ShowStatusBar=true

then in php block i check the value and trigger play

if ($value > $threshold)
echo <script> document.getElementById('WinMedia').Play();</script>";

but it doesn't play and sound.
What's the problem.

I added a js function for making the sound play
(in head tag):

          <script language=javascript>
          function fnPlaySound(){

Then I did the check and added a timeout to the onLoad event of the body for playing the sound

(in onLoad event on body tag):
if ($value > $threshold)
echo "window.setTimeout('fnPlaySound();', 1000);";
