Before you start
Prepare a safe repair session

Quick path
Try the safest checks first
Step 1
Pick the correct output device
Windows can route sound to HDMI, Bluetooth, monitor speakers, or a headset by mistake.
Exact path to follow
- 1Open Sound settings.
- 2Choose the intended output device.
- 3Check volume and mute.
- 4Play a short test sound.
Expected result
Sound plays from the correct device or the output device is confirmed missing.
If it worked
Stop here.
If it did not work
Check app volume and Device Manager.
Did choosing the output device restore sound?
Yes
Stop here.
No
Check mixer, app routing, and driver state.
Step 2
Check volume mixer and app routing
One app can be muted or routed to a different device while system sound works.
Exact path to follow
- 1Stay in Sound settings.
- 2Open Volume mixer if available.
- 3Check the affected app.
- 4Reset app volume or output routing if needed.
Expected result
The app is no longer muted or routed to the wrong output.
If it worked
Stop here.
If it did not work
Check Device Manager.
Did the quick path fix the problem?
Yes
Stop here and write down what worked.
No
Continue with the detailed steps below.
Detailed steps
Move one step at a time
Step 3
Check Device Manager
Device Manager shows whether Windows sees the audio device and whether it has a warning icon.
Exact path to follow
- 1Right-click Start.
- 2Open Device Manager.
- 3Expand Sound, video and game controllers.
- 4Look for warning icons or missing devices.
Expected result
You know whether the driver is present, disabled, or failing.
If it worked
Use rollback or reinstall only if the device shows a driver problem.
If it did not work
Install the official audio driver from the device maker.
Step 4
Roll back or reinstall the audio driver
If sound broke right after a driver update, rollback can be safer than installing a random new driver.
Exact path to follow
- 1Open the audio device properties.
- 2Use Roll Back Driver if available and the timing matches.
- 3Otherwise uninstall the device only if you have a restart path.
- 4Restart and test.
Expected result
Windows reloads or rolls back the audio driver.
If it worked
Stop and avoid extra driver changes.
If it did not work
Use the official manufacturer driver.
Step 5
Install the official audio driver
Laptop and motherboard makers often provide audio drivers matched to their hardware and enhancement stack.
Exact path to follow
- 1Find your exact laptop or motherboard model.
- 2Download the audio driver from the official support page.
- 3Install it once.
- 4Restart and test sound again.
Expected result
The output device returns and sound works.
If it worked
Stop here.
If it did not work
Test another output device to separate hardware from Windows.
Advanced checks
Use only after the safe path
Step 6
Separate Windows from hardware
A broken jack, bad cable, dead speaker, or HDMI monitor behavior can look like a driver problem.
Exact path to follow
- 1Test another headset or speaker.
- 2Try another port if available.
- 3Check HDMI monitor volume if using HDMI.
- 4Test Bluetooth audio with the Bluetooth guide if wireless.
Expected result
You know whether the issue follows the device, port, or Windows.
If it worked
Use the matching related guide.
If it did not work
Ask for hardware diagnosis if every output fails.
Stop here
Stop before hardware repair
Audio ports, speakers, and laptop ribbon cables are hardware repairs, not settings fixes.
- Stop for liquid damage.
- Stop if the port is broken or loose.
- Stop if opening the laptop is required.
Mistakes to avoid
- Do not reinstall Windows for one muted app.
- Do not install random codec packs.
- Do not use fake driver updater, repair, optimizer, or registry-cleaner tools.
When to ask a technician
- The audio jack is physically loose or damaged.
- Speakers crackle after liquid damage.
- No output works after official drivers and hardware tests.
Guided repair FAQ
Why does sound come from my monitor?
HDMI or DisplayPort can become the default audio output. Pick the intended device in Sound settings.
Should I uninstall all audio devices?
No. Change one device at a time and restart before deciding the next step.
Why does NexyFix avoid one-click repair tools here?
They usually hide what changed. This guide keeps each repair step visible, reversible, and tied to the symptom you actually see.
What note should I keep while testing?
Write down the exact error, device name, setting, cable, update, or hardware clue that changed the symptom. That note helps choose the next narrow guide.
