How to Fix No Sound or Audio Not Working

Tap a method to see how it works.

Check the volume and mute setting

It sounds basic, but this is the most common cause β€” first make sure the volume isn't set to zero and that mute hasn't been turned on.

Check which output device is selected

If multiple output devices like speakers and earbuds are connected at once, sound may be playing through a different device than the one you expect, so check the selected output device in your settings.

Update the audio driver (PC)

Updating or reinstalling the sound driver in Device Manager resolves the issue in many cases.

Restart the app or the device

If only one specific app has no sound, restart that app first. If the problem affects everything, restarting the device itself is worth trying.

Start with the basics before assuming a hardware fault

Sudden silence feels alarming, but it is far more often caused by a muted volume slider or a mis-selected output device than by a broken speaker. Working through the simple checks first saves you from an unnecessary repair.

When only headphones or Bluetooth audio has no sound

If wired or wireless headphones specifically have no sound, first confirm that the correct output device is actually selected in your settings, then check the Bluetooth pairing status if applicable. Removing and re-pairing a Bluetooth device often resolves an intermittent connection issue.

Frequently Asked Questions

Sound works through speakers but not through headphones.

Check whether the correct output device is selected in your settings, and if you are using Bluetooth, confirm that the pairing is active and stable.

There's no sound in just one app, but everything else works fine.

Check that specific app's own volume and output settings and its permissions, and try reinstalling the app if the problem persists.
