No sound in exported .flv movie


I’m having some problems with the playback of my exported flashmovie.
I’m using vlc mediaplayer but it says it doesn’t support the .undf sound that toonboomanimate outputs. Is there any way I can change the soundformat of exported animations.
If not, does anybody know which player to use thats supports .undf sound playback?


Why not try Flash Player 9 update 3 or later to view the .flv?
There are also many other free FLV players available from the web.
