Flash and Flex swc... and a little bit of Blazeds

Question

i have created a flex library project that connects to a BlazeDS endpoint for consumer/producer communication... i have used action script rather than configure the config.xml file on the server...  heres a snip of the code...
channelSet = new ChannelSet();
var channel:AMFChannel = new AMFChannel("my-amf", "http://localhost:8400/test/messagebroker/amf");
channelSet.addChannel(channel);
consumer = new Consumer();
consumer.channelSet = channelSet;
consumer.destination = "myEndPoint";
consumer.subscribe();
consumer.addEventListener(MessageEvent.MESSAGE, test);
producer = new Producer();
producer.channelSet = channelSet;
producer.destination = "myEndPoint";
producer.addEventListener(MessageAckEvent.ACKNOWLEDGE,  acknowledgeHandler);
producer.addEventListener(MessageFaultEvent.FAULT, faultHandler);
public function SendMessage(sendMe:String):void {
try{
     trace("sending message" + sendMe);
     var message:AsyncMessage = new AsyncMessage();
     message.body = sendMe;
     producer.send(message);
catch(error:Error){
     trace(error.message);
private function faultHandler(event:MessageFaultEvent):void{
      trace("not sent ---> " + event.message);
so i create my swc library... import it to a test flex app... and every thing works as it should.... which is great
when i import this swc to  flash cs4  i get an interesting error... i get a   MessageFaultEvent from the producer who cant seem to send a message to the endpoint....

seems like a url error?
anybody?
thanks

I usually follow these steps from Gyroplast to get my sound working
1. Run pacman -S {alsa-driver,alsa-lib,alsa-utils,alsa-oss}, in this order.
2. run depmod -a to make the newly installed modules known for dependency checks.
3. Identify which module to use for my soundcard; http://www.alsa-project.org very quickly told me that I'd need to load  snd-emu10k1.
4. Add this to your /etc/modules.conf:
# Sound (ALSA)
alias char-major-116 snd
alias snd-card-0 snd-emu10k1
post-install snd-emu10k1 /usr/sbin/alsactl restore
pre-remove snd-emu10k1 /usr/sbin/alsactl store
alias sound-slot-0 snd-card-0
# Soundcard 1 (OSS Emulation)
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
# Sound lookup entries for devfs support
alias /dev/dsp sound-service-0-3
alias /dev/sequencer sound-service-0-1
alias /dev/mixer sound-service-0-0
5. Run depmod -a again. Kills the warning.
6. Edit your /etc/devfsd.conf and add this:
# Allow access to sound devices for group "audio"
REGISTER ^sound/.* PERMISSIONS root.audio 0660
REGISTER ^snd/.* PERMISSIONS root.audio 0660
# Load ALSA sound when needed
LOOKUP snd MODLOAD
LOOKUP dsp MODLOAD
LOOKUP mixer MODLOAD
LOOKUP sequencer MODLOAD
note:  make sure you have an "audio" group and your userid is added to it!
7. That's nearly it. Now open your /etc/rc.conf and add  snd-emu10k1 to the MODULES array.
8. Reboot to test, run alsamixer afterwards to set the volume, and try out any sound application. Everything should run just fine, and mixer settings are automatically preserved
