Audio keeps breaking for the video created by Adobe After Effect CS 5.5

I created a video using Adobe After Effect CS 5.5 and imported a MP3 file to the time line -

 

After rendering the video to a movie with .avi format, the audio keeps breaking during the show time.

 

basically the audio stops during the video and then starts again, stops and then starts again - and

it is really annoying.

 

I tried to change it from 16 bit to 8bit and 32 bit but nothing changed -

really appreciate any help, thanks

 

Here is some info about the video :

 

----Video----

Frame width : 1280

Frame height : 720

Data rate :    552978 kbps

Total bitrate: 554389 kbps

Frame rate: 25 frames /seconds

---- Audio---

Bit rate: 1411 kbps

Channels: 2

Audio sample rate: 44 kHz

    The flaw is here:

    and imported a MP3 file to the time line

     

    Convert it to a WAV.

    Do a little generic research on video compression, CoDecs and formats. that's nothing anyone can explain in 5 minutes. If the audio plays fine in your MP4 file, then it could be merely a data rate issue with wjhatever settings you chose for your AVI, but really, do a little reading and come back with more specific questions after that.
