when you change the frame rate after you have made an animation, poser normally tells you that changing the frame rate may effect the output, ive tried re adding,and the sound is always out of sync, but i think the only solution(if you are using mimic change the frame rate in mimic before you save the pose file) is to export the file and then add the sound as a track like you can do in quick time pro, that way u can change the frame rate and try and synch the sound, but im only a newbie...
