No Sound on Windows? 10 Fixes for Audio Problems
You click play and hear nothing. Sound problems are common after updates, when connecting new devices, or when Windows chooses the wrong output. Work through these fixes in order; most people solve it in the first few steps.
1. Check volume and mute
Click the speaker icon on the taskbar and make sure volume isn't at zero or muted. Also check the volume inside the app or website itself, such as the YouTube player, and physical volume knobs on speakers.
2. Choose the correct output device
Windows may be sending sound to the wrong device, like a monitor without speakers or disconnected headphones. Click the arrow next to the volume slider in Quick Settings (Windows + A) and select the right device.
3. Check cables and connections
Make sure speakers are plugged into the green audio jack and powered on. Try headphones in the same port to test. For HDMI monitors or TVs, make sure the TV's own volume is up.
4. Restart your PC
A restart fixes temporary glitches with audio services.
5. Run the audio troubleshooter
Go to Settings → System → Sound, scroll down and click Troubleshoot common sound problems for output devices.
6. Check the volume mixer
Open Settings → System → Sound → Volume mixer. Individual apps can be muted or set to a different output device here.
7. Update or reinstall the audio driver
- Open Device Manager and expand Sound, video and game controllers.
- Right-click your audio device (often Realtek or Intel) → Update driver.
- If that doesn't help, choose Uninstall device and restart; Windows reinstalls it automatically.
- Laptop users should download audio drivers from the manufacturer's support page.
8. Turn off audio enhancements
In Sound settings, select your output device and look for Audio enhancements. Turn them off. Enhancements sometimes conflict with drivers.
9. Restart the audio service
Press Windows + R, type services.msc, find Windows Audio, right-click → Restart.
10. Change the audio format
In the device's properties in Sound settings, try a different Format, such as 24-bit 48000 Hz, and test.
Fixes for specific sound problems
Sound crackles or pops
Crackling often comes from driver issues, a busy processor, or power-saving settings. Update the audio driver, close heavy apps, and set the power mode to Balanced or Best performance when plugged in. Also try a different audio format in the device properties. For USB headsets, try a different USB port directly on the PC.
Headphones not detected
If the 3.5 mm jack doesn't switch output to headphones, open the audio manufacturer's app (such as Realtek Audio Console) and check jack detection settings. Clean dust from the jack gently and make sure the plug goes in fully; thick phone cases sometimes prevent this.
Microphone not working
- Check Settings → Privacy & security → Microphone and allow access for apps and desktop apps.
- In Settings → System → Sound → Input, select the correct microphone and speak to see if the volume bar moves.
- Increase input volume if others say you sound quiet.
- In meeting apps, choose the same microphone in their audio settings.
Volume is too low even at 100%
Turn on Loudness Equalization in the device's enhancements (if your driver offers it), which boosts quieter sounds. Also check the volume in the app itself and in the Volume mixer. Laptop speakers are small; for louder, clearer sound, external speakers or headphones are the real fix.
Sound works in speakers but not HDMI
Select the TV or monitor as the output device and make sure the display's own volume is up. Updating the graphics driver often fixes HDMI audio, since HDMI sound runs through the graphics card. See connecting a laptop to a TV.
Frequently asked questions
Sound works in some apps but not others. Why?
Check the volume mixer, and check the app's own audio settings for the selected output device.
Why did sound stop after an update?
Updates can replace audio drivers. Reinstall the manufacturer's driver or roll back the driver in Device Manager.
