I'm currently getting errors that my PC sound playback system can't read certain audio files because I don't have the correct codecs installed.

I do have an old link to www.fourcc.org/indexcod.htm , but it seems not to exist any more.

Can anyone guide me to where I can find codecs of differing types, or any useful info on codecs, including any utilities that help you identify what is the codec one is looking for?
