DivX for Mac does not have SOUND

Hello, I have been searching to download the supporter for Audio for the DivX plus for Mac that I have in my Mac OSX, but could not find, I was hoping this site can make my life easier by having someone who used to have the same problem and are able to give me a link to download the supporter for audio for DivX plus.

When I play a video with DivX plus on my Mac, it says "You may need an additional audio decoder to play the soundtrack of this file.
This file contains a track in the Dolby AC3 Audio (code "8192") format. You may need to install a DirectShow decoder for this audio format in order to hear the soundtrack of this file."

Please help! X-S
