Can you provide a debug level 5 log (including all higher level verbose+ messages) from Asterisk that shows the playback operation?

For each file that it finds with a given file extension, it picks the best media file (where best is given by transcoding cost) that matches the channel capabilities. That works great when you have a file system that can be scanned quickly.

That way they both act like they're working with their own local filesystem but really it's shared but distributed. Maybe I'll change it to use URLs and serve the files from the app in the future. I feel like it's more elegant for the app to own everything and treat asterisk like a stateless service, but there's no immediate reason to change the status quo.
