I had the same problem, and here’s how I fixed it:
1. Edit the post in HTML view (not Visual)
2. Delete any previous Audio tag references (such as [audio mp3=...] etc.)
3. Manually enter the audio code in this format:
[audio:your_filename.mp3] No http, no nuthin’.
4. Update the post.
The file should play properly in the browser now, and will show artist/title if available.
NOTE: The file you want to play MUST be located in the Default Audio Folder that’s defined on the Audio Player Settings (General tab).
Good luck – I really hope this works for you!
