HTML5 Media MP3 player not appearing with Seasons theme

Hello,
I'm using omeka 2.0.2 with seasons theme. I can't figure out how to display a player for mp3 files linked to my items. HTML5 Media plug-in is activated and the player is displayed in the admin view, but not on the public one.
I tried to change the theme and switched to Berlin theme. The player was then properly displayed.
But I would like to keep on using seasons theme, how can this be fixed?

Thanks,
François.

I believe the theme configuration for Seasons allows you to choose whether you want a "gallery" view of your item files.

The "gallery" will show thumbnails and only thumbnails. Disabling the gallery option should display files normally and include the HTML5 Media player.

This perfectly answers my question, thank you very much!
