I am not really sure what is your setting for sound, but I guess you should Use the Stream setting for synchronizing your sound.
The sounds default to the Event synchronization, so if you want your sound to synchronize using the Stream option, you need to explicitly tell Flash to do this. Select the keyframe that contains the sound, and in the Property inspector, select Stream from the Sync menu.
Setting a sound to synchronize using the Stream setting is a simple process; however, there are a few things you should be aware of with sounds set to this synchronization type. First of all, unlike sounds set to synchronize as Event or Start, those set to Stream play only as long as there are enough frames in the layer in which the sound has been placed. So when you use stream sounds, make sure that you have created enough regular frames (non-keyframes) on the same layer, directly following the keyframe with the sound. You will be able to see where the sound ends, because Flash places a waveform in the timeline for your convenience. Another thing to be aware of is that it is inadvisable to choose to loop these types of sounds.
Hi! thank you for your reply.
I`m aware of the sound setting even and stream.I`m using stream since I need to be able to control my sound from a main swf.
Anyhow I was referring to the a minor sound distortion created by swf quicker when I export my swf.The sound is great and crisp before being imported, but when it is exported in my swf it losses its crispness.I have synchronized my settings to export my sound in a the highest resolution by SWF quicker,but still no good results.
Please any help will be greatly appreciated,
