Sound not working in BB2 while running on iPhone

For some reason none of my sounds are working when I run the game on my iphone. I have the volume up(tested with a video off facebook). I have the sound button on the home screen. It plays sounds when testing in Buildbox 2....Sound files are in the project in xcode and can play them there.

 

Mostly just a software issue.
Have you ever turned off the sound authorization of FB. If not, you can force restart the phone to shut down the apps completely.
The easiest solution, in my opinion, is to use Joyoshare iPhone System Recovery, which will repair the phone without data loss.

 

If you disabled the sound feature on FB, then you could close the app by force restarting your iPhone. If it doesn't work, then you are recommended to use the iOS system recovery to deal with it, which is very workable for me. Hope it also is helpful for you.
