How to Fix “No Sound” or Audio Issues on Any Device
What’s Happening
No sound issues usually come from wrong output device selected (most common), muted system or app-level audio, corrupt or outdated audio drivers, app-specific audio bugs or hardware issues (speakers, headphones, ports). Modern systems often route audio to the last connected device, which is why sound disappears.
Quick Fix
- Increase volume and make sure device is not muted
- Disconnect and reconnect headphones / Bluetooth devices
- Restart your device
- Play audio from a different app (YouTube, music, etc.)
