audio wont play on phone MOTO X

I used a text widget to put audio files(mp3) on the home page. They work perfectly on desktop, laptop and pad. But my Moto X does not play the files. They show up, but when I click they get a grey box at the end of the title where the TIME REMAINING usually goes and then nothing happens. Is this a bug or is there a trick I need to use? Please advise! Thansk
