The absence of sound is an anomaly that is not related to the Mazaam app, but to iOS. To resolve this issue, you can watch this video https://youtu.be/SDf1LDcE95Q to view “IPad Sound Problem, No Sound on iPad Games, iPad without Sound on Apps: easy fix – iOS9, iOS 8 & 7”. This video explains how to verify if all buttons and settings are adjusted properly for the sound to be audible. Once these verifications are done, if there is still no sound, follow the instructions provided in the video to proceed to the complete reboot of your device. If you have followed the previous instructions and there is still no sound on your app (which would be a very rare occurence), some people suggest changing the operating system language settings for the device, by choosing any other language and then going back the desired language.
