I do, they sound fine then, but in Brawl, it's screwed.
oh...
I had that problem once...
open the brstm... and save as brstm...
that might work...
my problem was a zip file extraction error...
I just re-extracted and it sounded fine

it sounds like static right...
or does it play the original sound??
also... you did check the loop in brbx??
