No Sound on Computer
Answer a couple of questions and get the exact fix.
What's happening with your audio?
Why does this happen?
No sound usually means the wrong output device is selected, something is muted, or an audio driver got tangled. The fixer below checks the most common causes first — most take under two minutes to resolve.
Common causes
- The wrong output device is selected (speakers vs headphones vs HDMI).
- The system or an individual app is muted.
- A USB or Bluetooth audio device dropped its connection.
- A missing or corrupt audio driver.
Symptoms
- No audio from any app.
- Speakers work but headphones don't.
- One specific app is silent while others play.
- Sound cuts out after a Windows update.
Frequently asked questions
Why is there no sound even though nothing is muted?
Check the output device in Sound settings — audio can route to a phantom device like an HDMI output. Select your speakers or headphones explicitly.
How do I fix the audio driver?
In Device Manager, uninstall the sound device under 'Sound, video and game controllers', then scan for hardware changes to reinstall it.
