in IOS safari sound keep in silence after visibility change

[Z2Y-zz]

• A bug in the API:
  • Phaser version(s): 2.11.1
  • What should happen: sound should play
  • What happens instead: can't play any sound, the audio context's state is running

maybe unsetMute not work correctly when visibility change

What causes the visibility change?

Hi @Z2Y I'm having a similar issue with Phaser 2.9.4, do you remember how you fixed it?
