How to Fix Notification Sound Not Working on OnePlus 13

When your OnePlus 13 stops playing notification sounds, it becomes easy to miss important messages, app alerts, and reminders. This issue may feel random, but it normally comes from sound settings, notification permissions, connected audio devices, or system features that silence alerts without you noticing.

Below are the most reliable ways to bring your notification sounds back.

Why Notification Sound Stops Working on OnePlus 13

• The phone is set to Silent or Vibrate mode.
• App notification permissions are turned off.
• Do Not Disturb is enabled.
• A Bluetooth device is connected and capturing audio.
• Volume levels are set too low.
• System bugs or outdated software.

Check Volume Levels.

Notification sounds do not play when the volume slider is low or muted. Adjusting this ensures alerts are loud enough to hear.

1. Press either Volume key, and then tap the three dots on the volume panel.
2. Adjust the Notification volume slider, and make sure it is set to a higher level.

Try sending yourself a message to confirm the sound works.

Switch Off Silent or Vibrate Mode.

Your OnePlus 13 might be in Silent or Vibrate mode without you realizing it. Turning these off brings notification sounds back immediately.

1. Press a Volume key, and then tap the sound icon at the top of the volume menu.
2. Choose Ring to ensure your phone plays sound for alerts.

Lock your device and send a test notification to verify.

Disable Do Not Disturb.

Do Not Disturb silences notifications completely. Turning it off restores normal alert behavior.

1. Open Settings, and then tap Sound and vibration.
2. Tap Do Not Disturb, and then toggle it off.

Check if apps now produce sound when receiving notifications.

Check App Notification Permissions.

If a certain app is silent while others work, it may not have permission to play sound. Enabling this brings sound back for that specific app.

1. Open Settings, and then tap Apps.
2. Tap the app you want to check, and then tap Notifications to ensure sound alerts are allowed.

You can also test by sending yourself a message through the app.

Disconnect Bluetooth Devices.

Your notification sound might be redirected to a Bluetooth headset or speaker. Disconnecting Bluetooth forces notifications to play through the phone’s speaker.

1. Open Settings, and then tap Bluetooth.
2. Turn Bluetooth off, or disconnect paired audio devices.

After disconnecting, try triggering a new notification.

Turn Off Bedtime or Focus Mode.

Modes such as Bedtime or Focus silence notifications to reduce distractions. Disabling them restores sound alerts.

1. Open Settings, and then tap Special features.
2. Tap Modes, and then turn off Bedtime or Focus.

Now check if notifications alert you normally.

Restart Your OnePlus 13.

A quick restart refreshes system processes and can restore sound when a temporary glitch blocks audio output.

1. Hold the Power key and Volume Up key, and then tap Restart.
2. Wait for the phone to reboot, and then test your notifications again.

Update the System Software.

Outdated software may contain bugs that affect notification sound. Updating ensures your phone gets the latest fixes.

1. Open Settings, and then tap System.
2. Tap System updates, and then check for available updates. Install any updates shown.

This often resolves sound issues that come from software errors.

Reset All Settings.

If settings are misconfigured, resetting them brings everything back to default without deleting personal data or files.

1. Open Settings, and then tap System.
2. Tap Reset options, and then tap Reset all settings.

After the reset, test again to confirm the sound is working.

Once you work through these solutions, your notification sounds on the OnePlus 13 should return to normal. Most cases come from silent modes, Do Not Disturb settings, or Bluetooth connections, and fixing them usually restores alerts right away.
