Desktop xerte audio play variable issue

In the desktop Flash version I'm using a SWF menu with a checkbox for the user to set 'trackingData.audioplay' to 0 (don't play) or 1 (play audio).

It works fine in preview mode, but when I run it off a web server, even though the value 0 or 1 is being passed to the page it won't run the audio file. I'm using {trackingData.audioplay} as the value in the 'Play' property. If I change this property to '1' it will play... but then I lose the ability of the user to turn it on or off. It's late, and I'm stumped. Anyone know what I'm doing wrong?

OK I think I understand what is happening. To run the files on a web server it appears that the 'stream' property needs to be added in the sound icon and set to 1. This, however, seems to override the value of the 'Play' property and play the file no matter what the 'Play' property is set to. Unless I'm misinterpreting this, I think the only option for the user to not have audio is by turning his speaker volume down.
