To embed live audio into a website, use the following line of code:
<iframe id="camera" src="http://[camera-IP]/audio.cgi" width="0" height="0" frameborder="0"></iframe>
where [camera-IP] is your camera's IP.
If you want to use this outside of your home LAN, you must setup port forwarding on your router.
I hope this solves a few problems!
P.S - You may have to wait a bit for the audio to kick in
