Thanks! I Got it to work.
I had two templates for the sound sample PHP page.
The one that started off with the following lines 1 through 6 gave the problem:
<?php require_once( "../webassist/security_assist/helper_php.php" ); ?>
<?php
if (!WA_Auth_RulePasses("VerifiedUser")){
WA_Auth_RestrictAccess("../../login.php");
}
?>
