audio on AVI video

[bulletb1331]

Hey guys, new to the forum so don't bite my head off if i've got this in the wrong section but here goes. I've recently downloaded a video thats just under a gig and when i play the file i get very intense feedback/interference/garbled audio throughout the entire video. I can still barely make out what is being said so the real tracks are there but extremely distorted. I've tried downloading it again with the same results. Here are some interesting things that finally got me to come here:
1. the original download was interrupted by a computer crash and I redownloaded after reboot
2. after noticing the problem the first time i redownloaded. it did not correct it
3. I've recently tried streaming the same video from 2 different sources on the internet which produced the same interference.
4. I've downloaded the video on another computer and it has worked fine.
5. I put the file on a data cd from the other computer and then tried to play it on my computer and had the same audio problems (even though the video works fine on the other computer)
6. my speakers work fine with everything else (so it isn't a speaker/computer problem as far as i know)

I'm usually pretty good at trouble shooting stuff until it works but this has got me stumped and slightly worried about future videos i download. Let me know if anyone has had similar problems and what you've done to fix it.

Start by identifying the audio content of the file. G-spot or Video Inspector or Media Info can do this. Then install the codec you are missing so you can play the file back correctly. My guess is that this is an AC3 (Dolby Digital) audio track, and your system is trying to play it back as analogue. AC3 through an analogue system (without decoding) produces pink noise.

You could also try playing it back with VLC or The KM Player.

Thanks for the advice. i ran the video through g-spot and it said it was 0x0055 MPEG-1 Layer 3 and 48000Hz 130 kb/s tot , Stereo LAME3.96r under info. It says the codecs are installed. Any thoughts with this new information?

Have you tried using VLC or The KM Player ? They use their own codecs, and so don't rely on the system codecs. If it doesn't play in these there is a good chance it is corrupt.

Great advice...didn't try that the first time around but the KML player works great....i owe you big

download k-lite codec pack

download k-lite codec pack

Please don't. Codec packs are a crap shoot that often break as much, if not more than they fix. Because they load your system with things you don't need, or may not even be aware of, it then becomes difficult to troubleshoot down the track when you finally do find out what got broke.

Friends do not let friends install codec packs.

It is a short step from k-lite to WinAVI and video hell.

Garbled audio. Could it be that one of the channels in the stereo audio file is inverted?
