Somethings wrong!

I have loved this app since day one. My son sleeps to the sounds at nap time and at night. Last night we tried playing it and the sound kept leaving. The app is running but no sound. We have it on all our devices. We tried our iPad, husbands phone, and my phone and it happens on all of them. It only play sound for a min or two then nothing! Please, fix! We need this for our boy to sleep!
