Sound cuts out when I export animation

[Dashiell]

The animation I have been working on has a problem when I export it. The sound cuts out half way through the clip, that's to say it's fine for three or four seconds and then it cuts out. The sound is fine in the normal workspace view, it's just exporting it that creates the problem. I did have the audio muted briefly when I was working on it, but then I switched it on again and it was fine. I've looked at my export options and there doesn't seem to be anything I'm doing wrong there. Can anybody suggest a reason why this is happening. Or should I just add the sound again and hope it doesn't happen the second time?

Thanks.

Select your Audio layer and double check to see if there was a rogue keyframe accidentally set when you muted it.

No, it wasn't that. In the end I just deleted the audio track and the switch frames for the mouth parts, reimported the audio and added the mouth parts again, and it worked fine. A mystery. Thanks for your help, and sorry to trouble you.
