Audio not playing in PHP vicidial

Trying to add audio to this - $location is audio URL:

if (strlen($location)>30)
    {$locat = substr($location,0,27);  $locat = "$locat...";}
else
    {$locat = $location;}
if ( (preg_match('/ftp/i',$location)) or (preg_match('/http/i',$location)) )
    {$location = "<a href=\"$location\">$locat</a>";}
else
    {$location = $locat;}
$u++;
echo "<tr $bgcolor>";
echo "<td><font size=1>$u</td>";
echo "<td align=left><font size=2> $row[12] </td>";
echo "<td align=left><font size=1> $row[4] </td>\n";
echo "<td align=left><font size=2> $row[8] </td>\n";
echo "<td align=left><font size=2> $row[0] &nbsp;</td>\n";
echo "<td align=center><font size=1> $row[10] </td>\n"; 
echo "<td align=left><font size=2> $location  </td>\n";
echo "<td align=left><font size=2> <A HREF=\"user_stats.php?user=$row[13]\" target=\"_blank\">$row[13]</A> </td>";
echo "</tr>\n";

}

I have tried this. The player shows up but its not getting the URL. I do see the URL in the element when I inspect it.

echo "<td align=left><font size=2> <audio controls> <source=$location type=\"audio/mpeg\"> Your browser does not support the audio tag.</audio>  </td>\n";

This is from the vicidail qc page
