I'm not exactly sure what sort of problem you're having, could you be a bit more specific about what's going on?
At this point the only thing I can think is going wrong is that you audio level isn't set all the way to your audio source. That would cause you to get no sound when you exported it.
Make sure to check that, and if that doesn't work then post some more info as to what's going on. I used to use WMM, so I can help you out.
MJ who?
