No sound, just movie - how can I fix that?

[yosemite]

hi,

yesterday, I have reinstalled my PC and now I dont get any audio out of my speakers, when I am watching a selfmade DivX (in different players) (that works last week still and other audio sources like MP3 works still now!)

Well, seems that I have forgot to install something, but what?

HI!

You need the AC3 filters to playback movies with AC3,if you check the "How to mux AC3"in Dooms audio guide i think you will find them.
