Audio cutted when exported with SWF video.

Help! My audio is cutted when i export it with SWF video. Always at the final part. I´ve tried update TB Studio, but the trouble its still there. Inside ToonBoom, it works fine, but when i play the video, the last part of the audio disappear!

Excuse my english, i am from Brazil.

Maybe the scene is too long that the audio is cut due to limit of resource? Or try wav if you were using MP3 in case due to the compression.
If it does not help at all, better contact support.
