Most 'no sound' faults on a laptop are output-device selection rather than broken speakers. Operating systems switch the default output when a headset, monitor or dock connects, and do not always switch back.
No Sound From Laptop Speakers? How to Fix It (Windows)
Quick answer: If your laptop speakers have no sound on Windows, the cause is usually the wrong output device selected, the volume muted, or a driver problem — not broken speakers. Check the output device and volume first, then run the audio troubleshooter and update the driver.
Once sound is back, you can run the speaker test to confirm both the left and right channels are working.
Fix no sound on Windows, step by step
1. Check the volume and mute
Click the speaker icon in the taskbar and make sure the slider is up and not muted. Open the volume mixer too, in case a single app is muted while the system is fine.
2. Select the right output device
This is the most common cause. Windows often switches output to an HDMI monitor or a disconnected device that has no speakers. Go to Settings → System → Sound and, under Output, pick your laptop's speakers. If an external monitor with no speakers is set as default, that alone explains the silence. Plugging in or unplugging a monitor or headphones often leaves the output pointed at the wrong device afterwards, so re-check it whenever something was connected.
3. Run the Windows audio troubleshooter
Go to Settings → System → Troubleshoot → Other troubleshooters and run "Playing Audio". It can reset the audio service and reinstall the correct driver automatically.
4. Turn off audio enhancements
Badly configured enhancements can mute output. In Settings → System → Sound, open your speakers, scroll to Advanced, and set Audio enhancements to Off, then test again.
5. Update or reinstall the audio driver
Open Device Manager and expand "Sound, video and game controllers". A yellow triangle means a driver fault. Right-click your audio device (often Realtek or Intel Smart Sound) and choose Update driver. If that fails, choose Uninstall device and restart — Windows reinstalls it on boot. If the driver looks healthy, try restarting the audio stack instead: press Win+R, run services.msc, right-click "Windows Audio" and choose Restart. A mismatched sample format can also mute output, so in the speaker's advanced properties set a standard value such as 24-bit, 48000 Hz.
Why do my laptop speakers not work but headphones do?
If headphones play but the built-in speakers stay silent, Windows is routing sound to the headphone output, or the speaker driver has failed. Unplug the headphones, set the speakers as the default output device, and if they are still silent, update or reinstall the audio driver as above.
How do I know if my laptop speakers are blown?
Rule out software first. If external or Bluetooth speakers work, the volume is up, the right device is selected, and the driver is healthy — but the built-in speakers stay silent at every volume, or only crackle — the hardware is likely faulty and needs servicing. A quick way to split the problem: plug in headphones. If they play, the audio stack is fine and the built-in speakers or their connection have failed; if they are silent too, the fault is system-wide.
Confirm sound is back
After the fix, run the speaker test and play the left and right tones. If both sides sound clean, your speakers are working again.
Muffled rather than silent
If there's sound but it's faint or muffled, the cause is often physical. Many laptops have down-firing or side-firing speakers, so using the laptop on a bed, sofa or lap smothers them — moving to a hard desk makes an immediate, dramatic difference. Dust or debris in the speaker grilles also dulls the sound. And turning off "Loudness equalisation" and other enhancements can restore a fuller, clearer tone that virtual effects had thinned out.

Frequently asked questions
Why is there no sound from my laptop speakers?
Most often the output is set to the wrong device or the volume is muted. Select your laptop Speakers under Settings → System → Sound, check the mute key, run the audio troubleshooter, and reinstall the audio driver if needed.
My laptop speakers stopped working after unplugging headphones. How do I fix it?
The output is still routed to the headphone jack. Open Settings → System → Sound and select your Speakers under Output. Restarting the Windows Audio service via services.msc also clears a stuck routing.
How do I restart the audio service on Windows 11?
Press Win+R, type services.msc, find 'Windows Audio,' right-click it and choose Restart. This revives a frozen audio system without a full reboot and fixes many no-sound cases.
Why do my laptop speakers sound muffled?
Many laptops fire sound downward or sideways, so soft surfaces like a bed or lap smother them — use a hard desk. Clean dust from the grilles, and turn off audio enhancements that can thin the sound.
How do I know if my laptop speakers are blown?
Plug in headphones from the same laptop. If headphones play fine but the speakers stay silent or buzz, the speakers or their connection have failed. If headphones are silent too, it's a driver or settings issue, not the speakers.
Does the audio troubleshooter actually help?
Often, yes. It resets the audio service, checks the default device and routing, and re-applies the driver, which fixes a good share of no-sound cases automatically. Run it before manual driver work — it's quick and safe.
Why did my sound disappear after a Windows update?
Updates can replace the audio driver with a generic one or reset the default output device. Reselect your speakers under Settings → System → Sound, and reinstall the manufacturer's audio driver if the generic one misbehaves.
Why does my volume icon show a red X?
It means there's no active output device, or the current one is disabled. Click the icon and select a playback device, or open Settings → System → Sound to choose your speakers. Reinstall the audio driver if no device is listed.
