Playing mp3 stream works well in Emulator but doesn't play on Device

Question

I'm facing this problem. I'm using flex && actionscript to play an mp3 stream on the phone.
Code works great and the sound is played when the app is run in the flash builder emulator.
However, when i deploy my app on a mobile device (tried several Android phones) everything is good except the stream doesn't play!
Can you please help me??
Here's my code:
<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
                    xmlns:s="library://ns.adobe.com/flex/spark" title="HomeView"
                    creationComplete="view1_creationCompleteHandler(event)"
                    >
          <fx:Script>
                    <![CDATA[
                              import mx.events.FlexEvent;
                              import flash.net.*;
                              import flash.media.*;
                              private  var req:URLRequest;
                              private  var context:SoundLoaderContext = new SoundLoaderContext(8000, true);
                              private   var s:Sound;
                              private  var channel:SoundChannel = new SoundChannel();
                              private  function AudioOn():void
                                        req = new URLRequest("http://stream2.srr.ro:8000/;stream.mp3");
                                        s = new Sound(req,context);
                                        channel=s.play();
                              protected function view1_creationCompleteHandler(event:FlexEvent):void
                                        AudioOn();
                    ]]>
          </fx:Script>
          <fx:Declarations>

Answer 1

Okay.. First a big thanks!!
I've resolved the path issues and am now experimenting with formats other than SCORM that will hopefully launch off our LMS (SyberWorks).
I think I know what a cross domain issue is... it seems pretty self evident, (ie) .htm/.swf files live on a different server domain than video or audio files.
I think all my files are on the same domain in the zip file. However, are the following paths also an example of a cross domain issue?:
Z:\orgs\ogslp\courses\2012videotest\videotestinternalsrvr\videotestinternalsrvr.htm
(this is where I upload, or publish Captivate files)
http://gslcampus/ogslp/courses/2012videotest/videotestinternalsrvr/videotestinternalsrvr.h tm
(this is where clients access the training modules via IE & the Syberworks LMS, intranet)
One more..... when publishing with the Captivate > Internal Server option what path do I input to access the server?
Z:\orgs\ogslp\courses\2012videotest\videotestinternalsrvr\videotestinternalsrvr.htm
(backdoor for uploading files)
or
http://gslcampus/ogslp/courses/2012videotest/videotestinternalsrvr/videotestinternalsrvr.h tm
(actual internal, intranet url for accessing courses)
PS when I upload files the following appears before the Z:
Computer > SyberWorks (\\sousa)(Z:)
Any advice would be appreciated - thanks for your time.
