Ok, that makes sense. You add an additional soundstream to
the SWF, hence you get a "unsupported" SWF file with two
sound streams. (I very much doubt the Flash Player will play
both of them, probably it will select the first one, or even
play no sound at all)

So I guess what you need would be a way the strip a soundstream
from an SWF. The following python script should do the trick:

    #!/usr/bin/python2.3

    import SWF

    swf1 = SWF.load("input.swf")
    swf2 = SWF.create(version=swf1.version, bbox=swf1.bbox, fps=swf1.fps)

    for tag in swf1.tags:
        if "SOUNDSTREAM" not in tag.name: # soundstreamhead, soundstreamblock 
etc.
            swf2.tags += tag

    swf2.save("output.swf")
