MP3 no longer playing in FCPX
I am editing my wedding video and have a mp3 for the music I am using. Took a break and came back to it and mp3 no longer playing; waveforms are still there in the timeline but the audio won't play. Even when I try to re-import the music, it doesn't play and the waveforms have disappeared, but it will play in quicktime. All other audio in the project will play. Any suggestions would be appreciated.
