Alright. I want to convert an AVI file to an MP4 file. I go into Vegas (7d) and make the settings the same as the video that I want to convert (which has a full audio soundtrack) I import it and drop it into the timeline, and there's no audio track with my video track. I know that this file has audio in it, but for some reason won't show up in Vegas.

Any ideas as to what might be wrong?

You apparently don't have the audio codec used by that file installed.

Hmmm... How do I find out what it is? I installed DivX to play the video, shouldn't that cover the audio as well?

Not necessarily. You might try a program like "Gspot" to tell you want the audio codec is. Or just use some other program to convert the audio into something Vegas can see.
