I used Create Script > WAV file to create dialog for multiple characters in my scene. All audio files imported correctly and each character has a functional voice clip with synced mouth sprites.

However, there is no audio playing for one of the characters. This character has a voice clip track, and synced mouth movements, but I can't hear any audio in the project. I did a test export and he plays just fine. I need to hear his voice to animate him appropriately, can somebody help me with this?

I've tried deleting and re-importing the voice clip. I don't want to rebuild the entire project from scratch, as it's a complex scene and I'm limited on time, but I don't know what other options I have.
