I have an AVI file with two audio tracks that I am trying to edit. When I open it in Media Player, it plays fine (I can hear both). However, Windows Movie Maker and Adobe Premiere CS6 both seem to ignore the second audio track, and I can't find an option for multiple. Is there a way I could combine them or make Premiere recognise that two exist?
You could import the file into Audacity, verify that the tracks play as you wish there and then export the track into a file format that is flat and will play both tracks as one, for example .mp3.
