Laptop No Sound? How to Fix It (Pakistan)
No sound from a laptop is, more often than not, a software problem rather than a hardware failure — a muted output device, the wrong playback device selected, or an outdated audio driver account for the majority of "no sound" cases we see, and all three are free to fix in a few minutes. A genuinely blown speaker or damaged audio circuit is real but less common than people assume.
This guide runs through the quick checks that catch most sound problems for free before you consider a repair, and covers what to check specifically if you've ruled those out and it really does look like a hardware fault.
Likely causes
- •Master volume or a specific app's volume muted or turned down without realizing it
- •The wrong output device selected — audio playing to an HDMI monitor, Bluetooth headphones, or a disconnected device instead of the laptop's own speakers
- •An outdated, corrupt, or disabled audio driver
- •A blown or physically damaged internal speaker
- •Liquid damage to the audio IC or a loose internal speaker cable
Diagnostic steps
- 1
Check the master volume and mute status
Click the speaker icon in the taskbar and confirm it's not muted and the slider isn't all the way down. It sounds obvious but this is genuinely one of the most common causes, especially after a video call app auto-mutes system audio.
- 2
Check the correct output device is selected
Right-click the speaker icon > Sound settings > Output, and confirm the laptop's own speakers are selected rather than an HDMI monitor, Bluetooth headphones, or another device that may have connected in the background.
- 3
Test with headphones plugged in
If headphones produce sound but the speakers don't, that isolates the fault to the internal speakers specifically rather than the audio system as a whole — a different, usually hardware-side fix.
- 4
Check individual app volume
Some apps (especially browsers) have their own independent volume/mute control accessible from the same taskbar speaker icon's mixer view — confirm the specific app you're using isn't muted separately from the system volume.
- 5
Update or reinstall the audio driver
Open Device Manager, expand Sound, video and game controllers, right-click your audio device, and choose Update Driver. If that doesn't help, uninstall completely and restart to let Windows reinstall a fresh driver automatically.
Tools: Device Manager (built into Windows)

Run the built-in audio troubleshooter
Go to Settings > System > Troubleshoot > Other troubleshooters > Playing Audio and run it — this automatically catches and fixes several common configuration issues without needing to dig through settings manually.
- 7
Check for a disabled audio device
In Sound settings, click "More sound settings" and check the Playback tab for any device shown as Disabled (right-click and re-enable it if so) — this happens occasionally after a Windows Update resets device states.
- 8
Check for any spill or drop history
If liquid was ever spilled near the speaker grilles or the laptop was dropped, either can damage the internal speaker or its connection even if the rest of the laptop works fine — mention this when getting it diagnosed since it changes the likely cause.

Get it professionally checked if all software fixes fail
If headphones work but the built-in speakers stay silent after a driver reinstall, it's very likely a hardware fault — a blown speaker or a loose internal cable. WhatsApp 0314 4000131 with what you've tried, or bring it in for a free diagnosis.
When to see a technician
If headphones produce sound but the internal speakers stay silent after a driver reinstall and checking the output device, if there's a spill or drop history, or if the sound cuts in and out or crackles rather than being completely absent, get it looked at — a crackling or intermittent sound (versus total silence) often points to a loose cable or a partially damaged speaker rather than a simple settings fix.
Estimated repair cost: Rs. 1,000 – 5,000 (driver-level fix free if it's software; loose speaker cable reseat mostly labour, around Rs. 1,000-1,500; speaker pair replacement Rs. 1,500-4,000; audio IC repair on the motherboard, less common, Rs. 2,500-5,000)
FAQ
My headphones work but the laptop speakers don't — what does that mean?
This isolates the problem to the internal speakers or their connection specifically, ruling out a broader audio driver or software issue since headphone output is working through the same audio system. It's most likely a loose internal speaker cable (a cheap fix) or a blown speaker (needs replacing).
Why did my sound suddenly stop after a Windows Update?
Windows Updates occasionally reset the default output device, disable an audio device, or install a generic driver in place of the manufacturer's proper one. Check Sound settings for the correct output device first, then try reinstalling the audio driver via Device Manager if that doesn't fix it.
Is no sound usually a software or hardware problem?
Software, in most cases — muted volume, wrong output device, or an outdated driver account for the majority of no-sound complaints, and all are free to check yourself in a few minutes. It's worth genuinely ruling those out before assuming you need a speaker replacement.
Does N.N Laptops repair laptop speakers?
Yes — speaker replacement runs Rs. 1,500-4,000 per pair, usually same-day if the part's in stock. We always check drivers and settings first during diagnosis too, since there's no point charging for a speaker replacement if a free driver reinstall actually fixes it.
Can liquid damage cause silent speakers without any other visible symptoms?
Yes — liquid residue near the speaker grilles or the audio circuit can cause silent or crackling audio without necessarily affecting the keyboard or trackpad, especially if the spill was mostly absorbed near the edges of the chassis. Mention any spill history when getting it diagnosed, even an old one.
