Unable to read file

Hello!
I am using Azure’s Text-to-Speech service, using standard settings in my application to generate audio. However, when I try to set the track using the API, but also when using the UI, I get:
RuntimeError: Unable to read file: ....\tracks\1720701093.6398666.wav
It is a valid audio file, I can open and listen to the audio just as usual.

Thanks in advance!

Well for one, the naming is just a string of numbers. Very strange. But two, you cannot have a “.” in a file name. So try renaming it something better.

If that does not work, there may be something with the audio compression in the file. You can attach here so we can have a look.
