Audio file does not display the audio player

Hi, everyone. I need help regarding the audio file. When I view the audio file that I uploaded it doesn't show the audio/mp3 player.  The player is showing/working on the first 3 songs that are uploaded, but it fails to show on the succeeding audio upload. I tried disabling the zaudio, same thing happens. I'm using elgg 1.6.1.

Does anyone knows what could be the problem?

Thanks
