Step 3: Toggle on Sounds to enable the app’s notification sound. Pro Tip: Look for apps whose Notification Styles are set to ‘Off’ or ‘Deliver Quietly’. Step 2: Tap the app whose notification sound isn’t working. Step 1: Launch the Settings menu and select Notifications. You should do that for every application that isn’t playing notification sounds on your iPhone. Tap Deliver Prominently to get the app back to playing notification sounds. Step 2: If the app is set to deliver notifications quietly, you should see a Deliver Prominently button. Step 1: Swipe the alert (in the Notification Center) to the left and tap Manage. To check if you haven’t set to an app to deliver notification quietly, follow the steps outlined below. Otherwise, the scheduled DND option will mute app notifications during the set period.Īnother reason why you aren’t getting notification sounds from an app could be because it (the app) has been configured to alert you of new messages without making a sound. You should also check that you do not have a ‘Do Not Disturb’ schedule on your device. Alternatively, navigate to Settings > Do Not Disturb, and toggle off the ‘Do Not Disturb’ option. To disable ‘Do Not Disturb’, tap the crescent moon icon in the Control Center. These indications suggest that you have ‘Do Not Disturb’ enabled on your iPhone. A notification card informing you that ‘Do Not Disturb’ is active will also be displayed when you lock your device. Open your iPhone’s Control Center and check for a crescent moon icon next to the battery percentage. If your apps do not give you sound alerts for new messages and updates, you should check whether ‘Do Not Disturb’ is active. When enabled, the iPhone ‘Do Not Disturb’ feature mutes your phone calls, text messages, and other app notification alerts.
