Good app for Tara spiritual fans

Very clever, with stunningly beautiful painting of Tara, really inspiring. However, I can hear no sound at all on my iPad mini, whose audio works properly (checked with other apps). Could it be that it because Deva Premals album is not available from iTunes store here in Italy? I like silent meditation though so its not gonna be a problem anyway.
