One of my tracks isn't playing
I’ve been working on a project in Audition that has two tracks in the multitrack: one with music and one with dialogue. I was working on it when it said there was an error reading the disk, so I should save and restart Audition. I saved and restarted my project, but then my first track (with the dialogue in it) was not playing. The music in the track below is still playing. You can see the sound waves on the track, but the sound meter does not move.
I am on a windows PC. I’ve tried changing audio hardware preferences, I’ve tried restarting my PC, I’ve tried to shift all sounds down a few tracks, I’ve tried looking at previous backups (but they did not play as well),
