Hello everyone~ I have a question to ask. Currently, I’m developing a game using Unity WebGL, which will be embedded in an iOS app. There’s an issue where no sound is played. I know this is due to the autoplay policy, so I’ve tried resuming the AudioContext state, but the situation hasn’t improved. I’d like to ask if Fmod has made any improvements in this area? Or does anyone have relevant experience? Thank you~
To add, especially after viewing a Google mobile ad and returning to the game screen, the sound effects almost always have no audio.
