Axel, thanks for the reply. iOS is displaying the client's desktop site. I've switched between mobile and desktop sites but no luck.
No sound effects on any device using iOS. I've tried with both school and personal iOS devices attempting to rule out any issue in MDM config but we're seeing the same issue on all iOS devices. Browsers on Android work fine, as do Windows desktop and macOS but any browser tested on iOS (Safari, Firefox, Chrome) yield the same result--no sound effects.
Is there a way to enable auto-play in Safari on iOS? The only resources I can find are either outdated or demonstrate how to enable in Safari on macOS, but the latter instructions are not replicable in iOS. I've tested on another site that uses browser sound effects and getting the same results. I've also adjusted various settings in Notifications, Sounds, Motion, etc., including a factory reset on one device, but still nothing. The developer is suggesting enabling auto-play or trying another browser but I'm coming up empty handed.
I appreciate the help.
