"Can't locate audio" on mobile devices.

Hi,

I’m currently developing a website for a band and I am using jPlayer for the Music page. I’m using Custom Post Types so they can create playlists and Advanced custom fields for them to select .mp3’s to go in each playlist, which returns the ID of the song. I’m pushing the ID’s into an array ($song_ids) and using this to create the players:

<?php echo do_shortcode('[playlist artists="false" images="false" ids="' . implode(",", $song_ids) . '"]'); ?>

This works great on desktop but fails to work, with the error “Can’t locate audio”, on mobile devices. I’ve tested on iOS (Safari, Chrome, Opera) and Android (Chrome, Opera, Firefox, CM12 Browser) using an iPod Touch 4Gen, Samsung Galaxy S5, Samsung Galaxy Note 10.1 and HTC One. It’s worked on all desktop browsers I’ve tried (Chrome, Firefox, Safari and Opera), all on OSX.

Thanks in advance,
Oli.
