Macbook Safari Notifications Have no Sound

Re: I have sound notification on for Safari : But when I get a new notification, there's no sound.

If you haven't already: Try turning the setting off, and then back on,

If still no sound: Try restarting your Mac (ie: Apple menu > Restart) and log back in.

If still no sound: In Safari >Settings > Websites > Notifications ... check websites have notification-permission

Also: Check Apple menu > System Settings > Sound > make sure alert volume iis sufficient

Check Apple menu > System Settings > Notifications : check you chose "Alerts" (not Banners)

Else: You might want to let Apple know: There's a web-form for Feedback available :Feedback - Safari - Apple
