Fix No Sound on PC in 5 Minutes in Australia with Same Day Tech Help
The fastest fix for no sound on PC is checking the output device and volume levels, testing with headphones, then running the Windows audio troubleshooter if the basics don’t work. Start with the output device selection, since Windows often defaults to the wrong one after an update or reboot. If that doesn’t work, move on to drivers, services and, as a last resort, hardware replacement.
TL;DR:
Ensuring the correct output device is selected and set as default can resolve most common sound issues caused by Windows resetting configurations during updates or reconnections.
Loose cables, faulty jacks, or damaged hardware are responsible for many sound problems, especially when plugging in new devices or using older equipment.
Disabling audio enhancements and adjusting advanced sound settings can fix conflicts that cause silence or distortion in specific apps.
Running the Windows audio troubleshooter and restarting audio services often clears software glitches without needing driver updates or hardware fixes.
Hardware faults, such as a failed sound card or onboard chip, usually require professional repair or replacement if troubleshooting reveals no software or connection problems.

Quick troubleshooting checklist: what to try in the next five minutes
Before diving into settings menus or driver downloads, rule out the obvious. Most audio problems come down to something simple: a muted app, the wrong output device or a loose cable.
Check the system volume and make sure it isn’t muted, then check the volume slider for the specific app you’re using.
Click the speaker icon in the taskbar and confirm the correct output device is selected, not a monitor or virtual device.
Unplug your headphones or speakers, plug them back in firmly, and try a different port if one is available.
Test with a different pair of headphones or an external speaker to work out if the fault is in the PC or the audio gear.
If none of that helps, run the Windows audio troubleshooter through Settings.
This order matters because it moves from the quickest checks to the ones that take longer. According to Microsoft’s guidance on fixing sound problems, audio issues are commonly caused by the wrong output device being selected, a muted volume, interfering audio enhancements or outdated drivers. A practical approach follows a clear escalation path: a five minute checklist first, then the troubleshooter and a service restart, then driver work if nothing else has fixed it. Working through the list in order means you’re not reinstalling drivers for a problem that a muted volume slider caused.
Check Windows output device and volume settings
Windows can only play sound through the device it thinks you want to use, and that setting resets more often than you’d expect, especially after plugging in a monitor with built in speakers or reconnecting a USB headset.
Open Settings, then System, then Sound, and look at the Output section. You should see a dropdown listing every playback device Windows has detected. If your speakers or headphones aren’t the selected option, choose them from the list and play a test sound to confirm.
Open Settings > System > Sound and select the correct device under Output.
Click the volume icon in the taskbar to open the quick volume control and check it isn’t muted.
Open the Volume Mixer from the same menu to check individual app volumes, since a browser or game can be muted independently of the system.
Right click the speaker icon, choose Sounds, and check the Playback tab for devices marked as disabled or shown as greyed out.
If you can’t find the device you expect in that list at all, right click inside the Playback tab and tick “Show Disabled Devices” and “Show Disconnected Devices.” A device that’s been disabled will appear greyed out with a down arrow, and you can right click it and choose Enable.
Setting a device as default is different from just selecting it for one app. In the Sound Control Panel, right click your preferred device and choose “Set as Default Device.” This tells Windows to route all system sounds and most app audio there unless an app specifically overrides it.
Pro Tip: If you use both headphones and speakers, set the one you use most often as default, then switch manually when needed rather than relying on Windows to guess.
It’s worth checking this every time sound stops working unexpectedly, because plugging in a new monitor, docking station or Bluetooth device is often enough to shift Windows’ default without any notification. This single step resolves a large share of “my sound just stopped working” situations, particularly on laptops connected to external displays.
Check cables, jacks and simple hardware faults
Software settings get blamed first, but a surprising number of audio problems are just loose or damaged cables. If you’ve confirmed the right device is selected and nothing is muted, it’s time to look at the physical connections.
Start with the basics: is the speaker plugged into power, and is the cable properly seated in both ends? For desktop PCs, audio jacks on the front panel sometimes aren’t wired correctly to the motherboard, so trying the rear jacks directly can rule out a front panel fault.
Inspect the cable running from your speakers or headphones and check it isn’t frayed, bent sharply or loose at either end.
Try a different USB port for USB speakers or headsets, and try the analogue jack on the back of the PC rather than the front panel.
Test with a pair of headphones or a Bluetooth speaker to check whether the problem is the PC’s output or the built in speakers themselves.
Check for an inline volume control on your headset cable or a physical volume dial on external speakers, since these are muted more often than people realise.
If you’ve got a spare cable sitting in a drawer, swap it in and see if that changes anything. A damaged 3.5mm cable or a worn USB connector is a common, cheap-to-fix cause that has nothing to do with Windows at all. Retailers like LANCAST stock replacement cables and peripherals if you need a known good one to test against.
Pro Tip: If sound works through headphones but not speakers, the fault is almost certainly in the speakers, their cable or their power supply, not in Windows.
This step is especially useful for laptops, where the internal speaker can fail due to age or a knock while the headphone jack still works fine. If headphones produce sound but the built in speakers stay silent, you’re likely looking at a hardware fault rather than anything you can fix through settings.
Disable audio enhancements and check advanced sound settings
Windows applies audio enhancements, like virtual surround sound or loudness equalisation, by default on many systems. These features sometimes conflict with drivers or specific apps and can cause silence, distortion or crackling rather than the improvement they’re meant to provide.
To check this, go to Settings > System > Sound, click on your output device, then look for “Audio enhancements” in the device properties. If it’s set to anything other than “Off,” switch it off and test playback again.
Open device properties for your output device and set Audio enhancements to Off or Disable all enhancements.
Check the Advanced tab in the Sound Control Panel and try a different default format, such as a lower sample rate, if audio is present but distorted or silent in specific apps.
Restart the app you were using after changing these settings, since some apps cache the audio configuration on launch.
Test playback again through both the Windows sound test and the actual app you were originally using.
Enhancements sometimes break rather than improve sound because they sit between the app and the driver, processing audio in ways the driver or app doesn’t expect. A mismatch here can mute the whole output or cause some apps to play sound while others stay silent. Turning enhancements off removes that layer entirely and is a low risk change you can always reverse.
Run the Windows audio troubleshooter and restart audio services
If the basic checks haven’t fixed things, the built in troubleshooter is the next logical step. It’s automated, reversible and designed to catch a wide range of configuration and driver issues without you needing to know what’s actually wrong.
Open Settings, go to System, then Troubleshoot, then Other troubleshooters, and run “Playing Audio.”
Follow the prompts, since the tool will test your output device, check for muted apps and scan for driver issues automatically.
If the troubleshooter doesn’t resolve it, open services.msc by typing it into the Start menu search bar.
Find “Windows Audio” and “Windows Audio Endpoint Builder” in the list, right click each, and choose Restart.
Test sound again once both services have restarted.
According to Microsoft’s guidance on missing or undetected audio devices, running the automated Audio troubleshooter through Settings or Get Help is a sensible early diagnostic step, since it can resolve common configuration, driver and service errors without manual intervention. Separately, Microsoft’s advice on audio problems after a Windows update notes that restarting the Windows Audio and Windows Audio Endpoint Builder services often fixes a “no audio output device” error without needing to touch drivers at all.
Pro Tip: Restarting these two services takes under a minute and doesn’t require a reboot, so it’s worth trying before anything more involved.
This step is particularly useful because it resolves cases where Windows technically detects your hardware but refuses to route sound to it, a situation that looks like a missing device but is often just a stuck service.
Update, reinstall or roll back audio drivers
When services and settings haven’t solved the problem, the driver itself is the next suspect. This takes longer, but it’s the fix most likely to work if sound has been broken for more than a day or if Device Manager shows an error next to your audio device.
Manufacturer drivers are generally the better choice over generic Windows drivers or third party driver updater tools. According to Dell’s support guidance on speakers and headphones, when basic checks fail, downloading and cleanly reinstalling the audio driver from the PC manufacturer’s support site, using the device’s service tag, often restores a missing or malfunctioning audio device. Manufacturer packages typically include audio codecs and supporting components that the generic Windows driver leaves out.
Third party driver updaters can install incompatible generic drivers that cause “no audio output device” errors, so sticking to the manufacturer’s own download page is the safer route.
To find the right driver, locate your PC’s model number or service tag, usually printed on a sticker on the underside of a laptop or the back of a desktop case, then search for it on the manufacturer’s support site.
Open Device Manager, expand “Sound, video and game controllers,” right click your audio device and choose Uninstall device.
Restart the PC, since Windows will often reinstall a generic driver automatically, then install the manufacturer’s driver package over the top.
If sound worked before a recent Windows or driver update and stopped afterwards, use “Roll Back Driver” in the device’s Properties under the Driver tab instead of reinstalling.
Only fall back to the generic Windows driver if the manufacturer no longer provides one for your specific model, such as on very old hardware.
If you’re not sure which driver matches your hardware, most manufacturer support pages let you search by service tag or serial number to get the exact match for your model rather than a generic download. Rolling back is usually quicker than a fresh install and is the safer first move when the timing lines up with a Windows update, since it avoids introducing a second change on top of the one that broke things.
Advanced checks: BIOS audio, Windows updates and other last-resort fixes
If you’ve worked through drivers and services and still have no sound at all, not even a device listed in Windows, the problem might sit below the operating system entirely.
Restart your PC, enter BIOS or UEFI setup (usually by pressing Delete, F2 or F10 during boot) and check that onboard audio hasn’t been disabled in the settings.
Check Windows Update for pending updates, since a driver fix for your specific hardware may already be waiting to install.
If sound plays but sounds wrong or cuts out, try a different sample rate or bit depth in the Advanced tab of the Sound Control Panel for your output device.
If none of the above changes anything and the device never appears in Windows or Device Manager, the sound card or onboard audio chip itself may have failed.
A completely absent audio device, one that never shows up no matter what you try, usually points to a hardware fault rather than a software one. At that point, replacing a discrete sound card is often simpler than chasing a diagnosis further, while a failed onboard chip on a laptop typically means a technician needs to look at the motherboard itself.
When to call a technician and what to expect from an on-site visit
Some audio problems aren’t worth solving alone, especially once you’ve spent an hour on settings and drivers with nothing to show for it. A few signs point clearly to bringing in help rather than continuing to troubleshoot.
No audio devices appear in Device Manager or the Sound Control Panel at all, even after reinstalling drivers.
Sound cuts out intermittently after every fix you try, suggesting a deeper hardware or driver conflict.
You suspect a hardware fault, like a failed sound card or damaged port, but don’t have the tools or confidence to check it.
A technician visiting your home will typically start by testing your hardware directly, checking whether the issue is the port, the speaker or the motherboard itself. They’ll reinstall or roll back drivers if needed, restart the relevant services, and check for conflicts with other software running on the PC. If a component has genuinely failed, they can talk you through repair or replacement options on the spot rather than leaving you to work out the next step yourself.
Author perspective: practical priorities when troubleshooting audio
The biggest mistake people make with a silent PC is jumping straight to reinstalling drivers, the most time consuming fix, before ruling out anything simpler. Working through checks in order, output device first, then cables, then services, then drivers, saves hours of unnecessary effort and avoids introducing new problems along the way.
Clear, methodical steps matter more than clever ones. Most people don’t need jargon, they need to know what to click and in what order, and a calm explanation of what went wrong saves far more frustration than a quick fix that leaves them unsure what actually happened.

FAQ
Why does my PC suddenly have no sound?
The most common causes are the wrong output device being selected, a muted app or system volume, an outdated or corrupted audio driver, or enhancements interfering with playback, according to Microsoft’s troubleshooting guidance. A recent Windows update is also a frequent trigger if the problem started right after one installed.
How do I get my sound back on my PC?
Start by checking the output device and volume settings, then test with headphones to isolate whether the fault is hardware or software. If that doesn’t work, run the Windows audio troubleshooter through Settings, which can automatically fix common configuration and driver issues.
How do I reset sound settings on my PC?
Restarting the Windows Audio and Windows Audio Endpoint Builder services through services.msc is the closest thing to a sound reset and often fixes missing device errors without reinstalling anything. If that doesn’t help, uninstalling the audio driver in Device Manager and restarting lets Windows reinstall a clean version.
How do I unmute my PC’s audio?
Click the speaker icon in the taskbar and check the volume slider isn’t set to zero or crossed out, then open the Volume Mixer to check individual apps aren’t muted separately. It’s also worth checking for a physical mute button or inline volume control on your headphones or speakers, since these get bumped accidentally.
When should I call a technician instead of troubleshooting myself?
If no audio device appears in Device Manager after a driver reinstall, or sound keeps cutting out no matter what you try, the fault is likely hardware related and worth having a technician check. A home visit lets someone test your speakers, ports and drivers directly rather than continuing to guess.
