AVI no audio - 0x6771 Ogg Vorbis 3 PLUS

Tags: audio

I've just downloaded an AVI movie and when I played it there was video but no audio. Clearly it was a codec problem, but how to resolve it? Codecs are those pieces of software in your system responsible for decoding video and audio. Without the right codec, you're stuffed.

I started by downloading GSpot, a piece of software which will tell you (among other information) the codecs a movie uses and whether or not you have them installed. After running GSpot and dropping my problem file onto it I could see clearly that I did not have the codec to decode the audio. It even listed the codec I needed 0x6771 (Ogg Vorbis 3 PLUS).

Finding the right Ogg Vorbis codec has been a real pain though, and from the various forums I read, I'm not the only one. To simply visit the Ogg Vorbis site and download the latest codec was no solution. LINK UPDATED: 11 Aug 07 I found the version I needed here. Its a file listing as a web page so right click each file, choose save as, and then put them somewhere handy on your harddrive. Once you've got the files, on your HD (not in the web page) right click "vorbisacm.inf" and select install. This will register the codec on your system and hopefully you'll be away.

Other codec versions I tried resulted in still no audio or sometimes a deafening squealing noise. Seems this was the one for my problem file.

Update: I've kept a copy of the codec and will host it myself, if in the future I cannot find further links to it.
