Audio problems, possibly because of ac3 audio.

[xela06]

Hey everyone.

I recently downloaded a movie that is an .avi with ac3 audio. Right after I downloaded it, I tried to play it on the KMPlayer and all was well until about 2 minutes into the movie. All of a sudden the audio just stopped. I fast forwarded to the middle of the movie, and the audio was there, just ridiculously off. I figure there's about a 25 minute interval with no audio. Then it immediately starts off from where it left off. I tried playing it on many other players (Winamp, Windows Media, Quicktime, and DivX) and DivX was the only one that worked, but I had to download a codec for it. I would just use DivX, but the video quality is crap and it won't let me use the subtitles I need to watch the movie. Winamp and Windows Media did the exact same thing as the KMPlayer, and Quicktime wouldn't even play it. I was just wondering if anyone knew how to fix this.

Your help is very much appreciated.


UPDATE: I've been messing around with the video since I posted this, and I've found out that the audio is fine unless you fast forward or rewind. As soon as you do that, the audio gets all out of whack. I'm thinking it may be the ac3 filter, because when I used a different one on DivX, the audio was fine. I'm really not sure. I hope this helps in figuring out what's going on. It's driving me crazy! :mad:

Press Ctrl+Tab while playing the video file in KMP and paste here the report obtained.

Look at the AC3Filter configuration:

If you have an external codec pack that could be interferring, try to uninstall it.

I tried re-configuring the setting on the filter, and that didn't work. I also got rid of the other codec packs that I knew of. That didn't work either...

I'm not sure if it helps you but you can try this.

F2 - Goto internal audio decoder and enable AC3. (AC3 speaker setting should be 2/0; stereo) The internal ac3 decoder will be used.

Or try superspeed mode. --> alt+f
