I opened a short project (10 min video with several overlaid audio and video clips) that was working fine yesterday. Now, there is no audio when playing the video in the timeline, when dragging the "playhead" along the timeline, or when I export the sequence as an mp4 file.
However, if I open an individual video or audio clip in the mixer window, the sound works, so I know the audio is "there." I am an Adobe Premiere newbie. Any suggestions would be appreciated! Thanks.
