This hitch could be due to a system-wide configuration you made to your iPhone. The problem could also be app-specific, where you’ve accidentally made some in-app tweaks that muted the app’s notification. In some cases, the issue could be attributed to a bug in your iPhone’s iOS version. Whatever the case might be, refer to the solutions below to fix the problem with your iPhone’s app notification sounds.

1. Disable Do Not Disturb

When enabled, the iPhone 'Do Not Disturb' feature mutes your phone calls, text messages, and other app notification alerts. If your apps do not give you sound alerts for new messages and updates, you should check whether ‘Do Not Disturb’ is active. Open your iPhone’s Control Center and check for a crescent moon icon next to the battery percentage. A notification card informing you that ‘Do Not Disturb’ is active will also be displayed when you lock your device. These indications suggest that you have 'Do Not Disturb' enabled on your iPhone.

You should also check that you do not have a ‘Do Not Disturb’ schedule on your device. Otherwise, the scheduled DND option will mute app notifications during the set period.

    2. Disable Quiet Notifications

    Another 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.

    To check if you haven't set to an app to deliver notification quietly, follow the steps outlined below.

    Step 1: Swipe the alert (in the Notification Center) to the left and tap Manage.

    If you notice that an app no longer notify you via sound, you should check (and enable) the app’s sound notification. Follow the steps below to get it done.

    Step 1: Launch the Settings menu and select Notifications.

    4. Check In-App Notification Settings

    Some applications have their notification configuration that’s independent of your phone’s notification settings. If an app isn’t playing sound alerts for new messages, check its in-app notification settings and make sure sound alert is enabled.

    5. Reset All Settings

    Restoring your iPhone’s settings to factory default could also help to fix the app notification sounds not working issue on your device. Before you proceed with it, note that it will erase all previous configuration and personalization you’ve made to your device.

    Follow the steps below to reset all your iPhone’s settings.

    Step 1: Open the iPhone Settings menu and select General.

    6. Check Alert Tones

    Alert Tones are the sounds that your iPhone plays whenever a new message or notification drops on your device. If your iPhone has no Alert Tone selected for certain services and apps, your device will not play any sounds whenever there’s a new notification.

    Go to Settings > Sounds & Haptics > Text Tone. If the Alert Type is set to None, tap on the tones listed on the page to choose it as your text/notification tone.

    You should also return to the ‘Sounds & Haptics’ page and check that other services/apps (e.g., Mail, Voicemail, AirDrop, etc.) have their Alert Tones. If any of them is set to None, make sure you choose a notification tone.

    6. Update iOS

    One thing about Apple’s iOS and pretty much every other device’s operating system is that they mostly have one bug or another. The notification sounds issue does, sometimes, occur due to a bug in your iPhone’s OS. Luckily, OEMs do release system updates that squash bugs present in previous OS versions.

    You should also try to update your iPhone to the latest iOS version if none of the troubleshooting tips mentioned above yielded the desired result. Navigate to Settings > General > Software Update. Your device will check for available OS update for your device and prompt you to install it. Make sure your device is connected to the internet, though.
