I have a movie clip [AVI type] whose audio track will not play.

My DivX movie player [version 6.4.1.26] displayed a specific message that I needed to install a "Dolby AC3 Audio (code "8192") format DirectShow decoder."

I have downloaded and installed AC3 filter_1_11, to no apparent effect.

Is there a simplified solution as to obtaining the correct decoder that will do the job?"

It should work, but you may want to try another player since DIVX doesnt support AC3 audio.
BTW, next time use the search page on the forum. Similar topic found here.

I installed the AC3 filter and it didn't work in DivX for me either, but it did fix the sound issue I was having with Windows Media Player.
