Hello, I have had this problem for awhile now, NO SOUND AT ALL.
I haven't played Coral Island since I commented in another player's bug report, her 'no sound' is resolved, but mine persists.
I checked the files validity, uninstalled and installed back, deleted all save files and make a new one, but it solves nothing.
There is no sound starting from opening Coral Island home screen and gameplay throughout.
Please help, thank you.
