Missing notification sounds on the OnePlus 15 can cause you to miss important calls, messages, or app alerts. The phone may vibrate or show banners, but stays silent. This usually happens because of sound profiles, app notification settings, or system controls that mute alerts without you noticing.
Why Notification Sounds Are Not Working on OnePlus 15
- The phone is set to Silent or Do Not Disturb mode.
- Notification volume is turned down or muted.
- App notifications are disabled or set to silent.
- Bluetooth audio is connected and redirecting sound.
- System glitches after an update or prolonged uptime.
1. Check the Sound Profile
OnePlus phones use sound profiles that can mute notifications system wide. If the device is set to Silent, no notification sounds will play.
Open Settings, and then tap Sound and vibration.
Tap Sound profile, and then select Ring or Vibrate with sound enabled.
2. Turn Up Notification Volume
Notification sounds have a separate volume level from media and ringtones. If this slider is low, alerts will be silent even though other sounds work.
Open Settings, and then tap Sound and vibration.
Tap Volume, and then raise the Notification volume slider.
3. Disable Do Not Disturb
Do Not Disturb can block notification sounds while still allowing visual alerts. It is easy to leave this enabled by accident.
Open Settings, and then tap Notifications.
Tap Do Not Disturb, and then turn it off.
4. Check App Notification Settings
Some apps can be set to deliver silent notifications only. When this happens, the phone receives alerts without playing a sound.
Open Settings, and then tap Notifications.
Tap App notifications, and then select the affected app.
Enable Allow sound and make sure the notification category is not set to Silent.
5. Disconnect Bluetooth Devices
If your OnePlus 15 is connected to earbuds or a car system, notification sounds may play through that device instead of the phone speaker.
Swipe down from the top of the screen to open Quick Settings.
Tap Bluetooth, and then disconnect any connected devices.
6. Restart the Phone
Temporary system glitches can stop notification sounds from playing. Restarting refreshes system services and restores audio behavior.
Swipe down from the top of the screen to open Quick Settings.
Tap the Power icon, and then tap Restart.
Notification sound issues on the OnePlus 15 are usually tied to profiles, volume levels, or app settings. Once you restore the correct sound configuration, alerts should play normally again.
FAQs
Why do notifications vibrate but make no sound on my OnePlus 15?
This usually means the phone is in Vibrate mode or the notification volume is turned down. Switching to Ring mode and increasing notification volume fixes it.
Can individual apps mute notification sounds on OnePlus 15?
Yes. Each app can control its own notification sound settings, including silent alerts, even if system sound is enabled.
Does Bluetooth affect notification sounds?
Yes. When Bluetooth audio is connected, notification sounds may be routed to the paired device instead of the phone speaker. Disconnecting Bluetooth restores normal behavior.
