Theres no audio during the fight

The game is good and all but theres no audio during the fight. Back when I played the game there used to be audio during the fight itself but there isnt anymore. Now the only form of audio that I hear from the game when I play it is the music that plays the second I open up the app. Can you fix this problem please? Thank you.
