How to Fix Headphones Not Working on PC? | 7-Step Troubleshooting Guide

You can learn how to fix headphones not working on PC in about seven steps, starting with the output setting you probably overlooked. Whether you are using wired 3.5mm headphones, USB-C earbuds, or Bluetooth wireless models, Windows 11 and 10 both offer the same core fixes — and most take under two minutes each. The table at the end of this guide gives you a single reference for every fix by symptom, so you can skip straight to what your machine needs.

Why Do Headphones Suddenly Stop Working on Windows?

Headphones stop working on a PC for a short list of reasons, and the fix is almost never a hardware failure. The most common cause is Windows switching the audio output to speakers or a monitor after an update, driver conflict, or a Bluetooth handoff to another device.

The main culprits are:

• Wrong output device selected in Sound settings
• Realtek or generic audio driver conflict after a Windows update
• Bluetooth headphones paired to a phone instead of the PC
• Exclusive control mode locking the device for one app
• Dust or lint in the 3.5mm jack

Each of these has a direct fix below. Start in order — the first fix resolves most cases.

Headphones Not Working on PC? Start With the Output Check

The single most frequent reason headphones show no sound is that Windows is still sending audio to the built-in speakers or a monitor. Pointing it to the right output takes about ten seconds.

1. Open Start > Settings > System > Sound.
2. Under Output, look at the device name shown. If it says “Speakers” or your monitor name, click the dropdown and select Headphones or the Bluetooth model name (e.g., “WH-1000XM5”).
3. Check that the volume slider under Output is raised and not muted — a crossed-out speaker icon means mute is on.

For a deeper check, go to More sound settings (in the same Sound page) > Playback tab. Right-click your headphone device and select Set as Default Device. If the device is grayed out, right-click and choose Enable first.

Run the Windows Audio Troubleshooter

Microsoft’s built-in audio troubleshooter automatically detects common problems like exclusive control locks or driver glitches and offers a direct fix without you hunting through menus.

Windows 11: Start > Settings > System > Troubleshoot > Other troubleshooters > Audio > Run.

Windows 10: Start > Settings > Update & Security > Troubleshoot > Additional troubleshooters > Playing Audio > Run.

Follow the on-screen prompts. If it finds an issue, let it apply the fix. The troubleshooter is particularly good at resetting audio services that get stuck after a driver update.

Update or Roll Back the Audio Driver: The Realtek Problem

Audio driver conflicts — especially with Realtek High Definition Audio — are the second most common cause after a wrong output setting. Post-2025 Windows 11 updates have been known to break Realtek drivers on Acer Nitro, Dell, and HP laptops, leaving headphones silent.

1. Press Windows key + X and select Device Manager.
2. Expand Sound, video and game controllers.
3. Right-click your audio device (usually Realtek(R) Audio or Intel Smart Sound Technology) and choose Update driver.
4. Select Browse my computer for drivers > Let me pick from a list of available drivers.
5. If you see both a “Realtek” driver and a “Microsoft” driver, choose the Realtek-specific one. If only the Microsoft generic driver is listed, select Uninstall device, restart the PC, and let Windows reinstall it.

Rollback fix: If the problem started immediately after a Windows update, go back to Device Manager > right-click the audio device > Properties > Driver tab > Rollback Driver. This restores the previous working version. Microsoft’s official audio troubleshooting guide covers the full rollback procedure.

Disable Exclusive Control Over Audio Devices

Windows allows apps to take exclusive control of an audio device. When Zoom, Discord, or a game locks the headphones, other sounds go silent — even though the headphones are working.

1. Go to Settings > System > Sound > More sound settings.
2. In the Playback tab, right-click your headphone device and select Properties.
3. Open the Advanced tab.
4. Uncheck Allow applications to take exclusive control of this device.
5. Click Apply, then OK.

Also check the Levels tab in the same Properties window and confirm the volume slider is at 100 — some apps reduce it without you noticing.

Fix Bluetooth Headphones That Won’t Connect

Wireless headphones like AirPods, Sony WH-1000XM5, or Bose QuietComfort often auto-connect to a phone or tablet instead of the PC. The fix is to force a fresh pairing to Windows.

1. Open Settings > Bluetooth & devices (Windows 11) or Devices > Bluetooth & other devices (Windows 10).
2. Find your headphone name in the list, click the three dots or right-click, and select Forget.
3. Put your headphones into pairing mode (usually holding the power button for 5–10 seconds until the LED flashes).
4. On the PC, click Add device > Bluetooth and select your headphones when they appear.

If Windows still doesn’t find them, disable Bluetooth on your phone and any other paired device, then try again.

Clean the Audio Jack and Check the Hardware

A 3.5mm jack packed with dust or lint can prevent the headphone plug from seating fully, causing no sound or a one-sided connection. This is more common than most users expect — especially on laptops carried in pockets or bags.

Power off the PC completely. Dampen a cotton swab with a small amount of rubbing alcohol (never spray anything into the jack) and gently rotate it inside the port. Let it dry for 60 seconds before plugging in headphones. If sound returns, the connection was the issue.

The Headphone Fix Order That Works Every Time

Follow this sequence and you will resolve roughly 95% of headphone issues without needing any third-party tools or repairs.

1. Confirm the output device — Settings > System > Sound > Output. Select the right headphone.
2. Run the audio troubleshooter — it handles exclusive control and stuck services in one pass.
3. Update or roll back the audio driver — Device Manager > Sound controllers > Realtek driver.
4. Disable exclusive control — Sound Properties > Advanced tab > uncheck exclusive mode.
5. Re-pair Bluetooth headphones — forget the device, then pair fresh from the PC.
6. Clean the audio jack — a cotton swab and alcohol takes 30 seconds.
7. Test another pair of headphones — if a second set works, the original headphones may need repair.

If none of these restore sound, the audio jack or motherboard audio controller may be physically damaged — especially on laptops older than three years. Professional repair or a USB audio adapter is the next step.
