Audio and slide out of sync sometimes on HTML5 output

Problem: I have some buttons that on rollover show shapes with text in them and on rollout hide the shapes. When the shapes are shown/hidden the audio ends up out of sync, slide timeline ends up behind audio, can be up to 0.5-1 second. The more you rollover/rollout out the worse the syncing becomes, it seems like the showing/hiding of the shapes is slowing down the timeline but not the audio.
