title: How can I call an AMF service using Flex and get back an MP3?
body: <p>My flex 3.5 application has an audio player whose content is accessed by calling an AMF service to get the mp3 data. As far as I can tell, <code>flash.media.Sound</code> is initialized with a <code>URLRequest</code>, so it's not clear to me how I can provide it with data using my <code>RemoteObject</code>.</p>
  
  <p>I want to do one of the following things:</p>
  
  <ol>
  <li>Provide data to the <code>Sound</code> object's <code>load</code> method from a <code>RemoteObject</code> service call.</li>
  <li>Create a <code>URLRequest</code> object that will perform the requisite AMF wrapping so that my service implementation will look exactly like any other service call if at all possible.</li>
  <li>Any alternative that allows me to invoke a PHP4 AMF service and play the audio it returns in a Flash audio player.</li>
  </ol>
