Not really. This is the best place to come and describe the problem. What that often does is take the asker off on a journey around the wiki and the search function of this site - while some of the rest of us chip in with suggested-answers that probably aren't correct ... but send you on a longer journey around the wiki/search-function.
Then, the asker usually finds the answer, somewhere roughly related, and we all go back to sleep waiting for the next person-with-a-problem to drop by and start the cycle all over again

Glad you found and fixed it, mate ... I can see why the bug caused the issue (the scene never finished), though I am surprised that the system did not ignore the bad audio-file and complete the scene anyway - So we all learned something

And thanks for coming back and posting the fix; now when someone else gets the issue they have another vector to search on!
GL with your Mod ... You know where we all are if/when you need to set yourself off on another problem solving quest
