Laptop Audio Not Working? 8 Fixes to Try Before Calling a Technician

No sound from your laptop? Most audio problems are software-related and fixable in minutes. Work through these fixes in order — each one takes less than 5 minutes.

Common causes of laptop audio not working:

Volume muted or default output set to wrong device
Corrupt or outdated audio driver (especially after Windows updates)
Windows Audio service has crashed
App-specific audio setting pointing to wrong device
Physical hardware fault — blown speaker or faulty headphone jack

Check the obvious first — volume and mute

Before anything else: is the laptop muted? Click the speaker icon in your taskbar (Windows) or menu bar (Mac) and make sure the volume is turned up and not muted. Also check the physical volume keys on your keyboard — some laptops have a dedicated mute key that is easy to press accidentally. If you are using headphones, try unplugging them and using the built-in speakers instead to isolate the issue.

Check the default playback device

Windows often switches the default audio output when a device is connected or disconnected. Right-click the speaker icon in the taskbar → Open Sound settings → scroll to Output → make sure the correct device is selected (usually "Speakers" for the built-in laptop speakers). On Mac, go to System Settings → Sound → Output and confirm the right device is selected.

Run the Windows audio troubleshooter

Windows has a built-in audio troubleshooter that fixes the majority of common sound issues automatically. Right-click the speaker icon in the taskbar → Troubleshoot sound problems. Follow the prompts. This fixes corrupted audio settings, missing driver registrations and misconfigured playback devices in most cases.

Update or reinstall the audio driver

A corrupt or outdated audio driver is one of the most common causes of laptop audio not working — especially after a Windows update. Open Device Manager (search for it in the Start menu), expand Sound, video and game controllers, right-click your audio device (usually "Realtek" or "Intel") and select Update driver. If the device has a yellow warning icon, right-click and Uninstall device, then restart your laptop — Windows will automatically reinstall a fresh driver.

Check if audio is working in a specific app only

If audio works in some apps but not others (e.g. works in YouTube but not Zoom), the problem is app-specific, not a system fault. Check the app's own audio settings and make sure it is not set to use a different output device. In Windows 11, individual app volume can be controlled via Settings → System → Sound → Volume mixer.

Restart the Windows Audio service

The Windows Audio service occasionally crashes and does not restart automatically. Press Windows + R, type services.msc and press Enter. Scroll to "Windows Audio", right-click and select Restart. Also restart "Windows Audio Endpoint Builder" the same way. This takes 30 seconds and fixes the issue surprisingly often.

Check for Windows updates

A pending Windows update can sometimes hold back audio driver updates or include fixes for known sound issues. Go to Settings → Windows Update → Check for updates. Install any available updates and restart. This is particularly relevant if sound stopped working after a recent Windows update — Microsoft often issues follow-up patches.

Test with external speakers or headphones

Plug in a pair of headphones or external USB speakers. If audio works through them but not through the built-in speakers, the fault is almost certainly a hardware issue — either a blown internal speaker or a faulty speaker connection. This is a fixable hardware repair that a technician can resolve on-site. If audio does not work through external devices either, the fault is in the audio circuitry, which also requires professional diagnosis.

When to call a technician

If you have worked through all 8 fixes above and audio is still not working, the fault is almost certainly hardware. Common hardware causes include:

Blown internal speaker (requires speaker replacement)
Faulty or dirty 3.5mm headphone jack
Damaged audio IC chip on the motherboard
Loose speaker cable inside the chassis

Frequently asked questions

Why is my laptop audio not working?

The most common causes are muted audio settings, an outdated or corrupt audio driver, incorrect default playback device, or a hardware fault with the speaker or audio jack. Start with the software checks before assuming hardware failure.

How do I fix laptop audio not working in Windows 11?

Right-click the speaker icon in the taskbar and select Troubleshoot sound problems. If that does not help, open Device Manager, expand Sound controllers, right-click your audio device and select Update driver. If the driver is showing a warning icon, uninstall it and restart — Windows will reinstall it automatically.

Why does my laptop have no sound through headphones?

Most commonly this is a playback device setting. Right-click the speaker icon in the taskbar, click Open Sound settings, and check that your headphones are set as the default output device. Also try unplugging and re-plugging the headphones firmly — a dirty or loose jack is a common cause.

Can a technician fix laptop audio problems at my home?

Yes. TechFix Pro provides on-site laptop audio repair across Western Sydney. Most audio faults — driver corruption, blown speakers, faulty jacks — are diagnosed and resolved in a single visit. No Fix, No Fee.
