what are the requirements for the file in flash?
there may be something in the header bar
that is confusing flash!
try opening the file in notepad or wordpad...be patient, it may take a while to open
then look for clues at the top section that may be throwing off flash
when you scroll down [ after it opens in notepad ] you'll see the body of the wav file is
just special character gibberish, hence my comment to look for clues in the top section.
don't change ANYTHING in the lower section, that's the music/audio in code
good luck
