I've been using Premier Pro for several months now with limited problems but just recently I'm no longer able to get audio tracks to show up on the timeline of my projects. When I go into older projects and import new AVIs, the audio won't show up. If I select an older AVI that was imported before this happened, I can get the audio to show up.
This only seems to happen with AVI files where audio is compressed with mp3. AVIs with WAV audio are working. This is still odd though, b/c the mp3 AVIs were working fine several weeks ago.
