Music discs don’t play music

I can clearly see that the birds can hear the music but I cannot hear any music I can also see the music notes coming from the music box but I still hear no music. This has been a problem ever since they added music discs in pocket edition. I put a music disc in but the music does not play. In this picture you can clearly see that the parrot can hear the music and that there are music notes however I cannot hear any music coming from my phone speakers.
