No player displayed for Sound type

Hello. I have created a new test item with a Sound type file. The file I have uploaded is an mp3 file that the system recognizes as

Mime Type / Browser:
Mime Type / OS:
audio/mpeg; charset=binary
File Type / OS:
Audio file with ID3 version 2.3.0, contains: MPEG ADTS, layer III, v1, 48 kbps, 32 kHz, Monaural

The public page for the item is:

Unfortunately, no link for the mp3 file or media player is displayed.What might be the problem?

Thank you for your help.

I see a media player on that page, under the "Files" section.
