That's perfectly correct, dumpstream is supposed to dump the whole 
stream, that is video _and_ audio.

I would use mencoder to change the audio stream, maybe like

mencoder file.flv -audiofile audio.wav -ovc copy -oac copy -o result.avi

It's not sure however that an .avi-file with flv-encoded video plays on 
any player, but I think mplayer might do it.
