Hi :

I recorded an audio file for one of the lessons, and I tried to upload it, in order to get a review or comments, but once you upload it, if you click on it, you don´t get any sound, it gets stuck at 0:00, and you can´t play the file.

I tried uploading different audio file types (.MP3 or WAV) and it does not work in any of both formats. Is there something I need to know about the audio files that can be uploaded? Thank you
