Why There Is No Sound on a Laptop
A situation where a laptop suddenly loses sound is quite common. The system may appear to work normally, videos play correctly, but nothing can be heard from the speakers.
In many cases, the issue is not caused by hardware failure. The reason may be Windows settings, muted audio, a driver problem, or an incorrect playback device selection.
However, sometimes the lack of sound can indicate a problem with the speakers, audio jack, or motherboard.
How to Understand the Problem
Before starting troubleshooting, pay attention to the following:
- Did the sound disappear completely or just become quieter?
- Did the issue start after a Windows update?
- Did the sound stop working after connecting headphones?
- Is there no sound in only one application or throughout the system?
- Do headphones or a Bluetooth speaker still work?
Answering these questions can help identify the cause faster.
What to Check First
1. Volume Level
Start with the simplest check.
Click the speaker icon in the bottom-right corner of the screen and make sure the volume is not muted.
Also check the keyboard shortcuts:
Fn + the key with the speaker icon
Many laptops allow users to mute sound accidentally through the keyboard.
2. Selected Playback Device
Windows can automatically switch audio output to:
- headphones;
- a TV connected via HDMI;
- a Bluetooth device;
- an external monitor.
Path:
Settings → System → Sound
In the “Output” section, check which device is currently selected.
Try manually switching between available devices.
If the Sound Disappeared After Connecting a Monitor
This is a very common situation.
When an HDMI cable is connected, Windows often redirects audio to the monitor or TV.
How to check:
Settings → System → Sound → Output
Select:
- Speakers;
- Speakers (Realtek Audio).
3. Windows Audio Troubleshooter
Windows includes a built-in audio diagnostic tool.
Path:
Settings → System → Troubleshoot → Other troubleshooters → Playing Audio
Windows will automatically check for common audio problems.
4. Check the Windows Audio Service
If this service is stopped, audio will not work.
Press:
Win + R
Type:
services.msc
Find:
Windows Audio
The status should be:
- Running;
- Startup Type: Automatic.
Checking the Audio Driver
One of the most common causes is a driver issue.
How to Check
Path:
Win + X → Device Manager
Open:
Sound, video and game controllers
Common devices include:
- Realtek Audio;
- Realtek High Definition Audio;
- Intel Smart Sound Technology.
What to Look For
If:
- there is a yellow warning icon;
- the audio device is missing;
- Windows shows “Unknown Device”.
The problem may be driver-related.
How to Reinstall the Driver
In Device Manager:
Right-click the audio device → Uninstall device
Then restart the laptop.
Windows will often reinstall the driver automatically.

How to Check the Speakers
Try the following:
- connect headphones;
- connect a Bluetooth speaker;
- play sound through a browser and through a local audio file.
If sound works through headphones but not through the built-in speakers, the speakers themselves may be faulty.
If Only One Application Has No Sound
Sometimes the issue affects only a specific program, such as:
- a web browser;
- Zoom;
- Microsoft Teams;
- Discord.
In this case, check the audio settings within that application.
When the Problem Is Hardware-Related
Common symptoms include:
- crackling or distorted sound;
- one speaker not working;
- sound disappearing intermittently;
- headphones work but speakers do not;
- sound disappears when moving the laptop lid.
Possible causes:
- faulty speakers;
- damaged audio jack;
- damaged cable or connector;
- failed audio codec on the motherboard.
When Professional Service Is Needed
You should contact a service center if:
- reinstalling drivers does not help;
- Windows cannot detect any audio device;
- sound disappeared after a drop or liquid damage;
- speakers crackle or do not work at all;
- the issue returns after reinstalling Windows.
Conclusion
In most cases, the absence of sound on a laptop is related to Windows settings or audio drivers. These issues can often be fixed in just a few minutes without repair.
However, if Windows cannot detect the audio device or the sound does not return after reinstalling drivers, professional diagnostics may be necessary to rule out speaker, audio jack, or motherboard failure.
