Symptoms
- No sound plays even at full volume
- Sound works in other apps but not this one
- Audio plays through the wrong output like a paired Bluetooth device
- Video plays but with no sound
Likely causes
- CommonPhone muted, on silent, or volume turned downIt's easy to miss a silent switch or low media volume separate from ringer volume.
- CommonAudio routed to a connected Bluetooth deviceSound may be playing through headphones or a speaker you're not near.
- PossibleApp-specific mute or audio settingSome apps have their own internal mute toggle separate from phone volume.
- PossibleMissing microphone/media permission for the appSome apps require explicit permission to play or process audio.
- PossibleOutdated app version with an audio bugPlayback bugs are commonly fixed in updates.
What to do
- Check the phone isn't on silent mode and media volume is turned up (not just ringer volume).
- Check Bluetooth settings and disconnect any paired headphones or speakers you're not using.
- Check the app's own volume or mute control inside its interface.
- Confirm the app has needed audio-related permissions in phone settings.
- Restart the app and then the phone if the issue continues.
- Update the app to its latest version.
- Test another app's audio to confirm the issue is app-specific, not a phone speaker problem.
When to call a pro
If no app plays sound and the speaker itself seems silent, a repair shop should check for a hardware speaker fault.
