I'm glad you were able to get it working properly after replacing the file. Another thing you can do in the future is tap the settings icon at the top right corner of the audio player and toggle off "Use advanced audio player". This will switch from using a custom audio library to using core audio. This is another way to identify if there is an issue with the file itself, or if it's a compatibility issue with the custom audio library.
