Windows File Explorer Keeps Crashing: How to Fix explorer.exe Restarting Itself

Audio driver errors on Windows 11 are frustrating because sound issues can come from so many different places — the driver itself, Windows settings, a hardware conflict, or a recent update that broke something quietly in the background.

This guide covers all three of the most common audio problems: no sound at all, crackling or static noise, and headphones not being detected when plugged in. Each section has its own set of fixes, so jump to whichever problem matches yours.

Why Audio Drivers Fail on Windows 11

Before jumping into fixes, it helps to understand what’s actually going wrong.

Your audio driver is the software layer between Windows and your sound hardware — whether that’s a built-in Realtek chip, an Intel HD Audio device, or a dedicated sound card. When this driver is outdated, corrupted, or conflicting with another component, you get:

• Complete silence even though the volume is up
• Crackling, popping, or static during playback
• The system not recognizing headphones when plugged into the jack

Windows 11 also introduced some new audio handling behaviors that didn’t exist in Windows 10 — which is why some users started seeing these problems right after upgrading.

Quick Checks Before Anything Else

Run through these first. They take 30 seconds and solve the problem more often than you’d expect.

• Volume mixer: Right-click the speaker icon in the taskbar → Open Volume mixer — make sure no app is muted
• Output device: Click the speaker icon → check which device is selected. Windows sometimes switches to a wrong output after an update
• Physical connections: Check that speakers or headphones are firmly plugged in
• Mute button: Check if your keyboard’s mute key is active (many have an LED indicator)
• App-specific issue: Test sound in multiple apps — if only one app has no sound, the problem is that app, not the driver

If everything checks out and the problem persists, move on to the fixes below.

Part 1 – No Sound at All

Fix 1 – Set the Correct Default Playback Device

Windows 11 can switch your default audio output without warning — especially after updates or when you connect a new display via HDMI.

1. Right-click the speaker icon in the taskbar → Sound settings
2. Under Output, check which device is selected
3. If it shows something like “NVIDIA HDMI Output” or “Intel Display Audio” instead of your speakers, click the dropdown and select the correct device
4. Test sound immediately

This is the most overlooked fix — and it solves the problem in a large percentage of cases.

Fix 2 – Run the Windows Audio Troubleshooter

Windows 11 has a built-in audio troubleshooter that catches common configuration issues automatically.

1. Open Settings → System → Troubleshoot
2. Click Other troubleshooters
3. Find Playing Audio and click Run
4. Follow the on-screen steps and apply any suggested fixes
5. Restart your PC afterward

It’s not perfect, but it catches things like misconfigured services and wrong default devices quickly.

Fix 3 – Restart the Windows Audio Service

The Windows Audio service can stop or hang without crashing the whole system — leaving you with silence and no obvious error message.

1. Press Windows + R, type services.msc, press Enter
2. Scroll down to find Windows Audio
3. Right-click it → Restart
4. Also restart Windows Audio Endpoint Builder the same way
5. Test sound

If these services were stopped rather than just hung, right-click → Start instead of Restart.

Fix 4 – Update the Audio Driver

An outdated audio driver is one of the most common causes of complete sound loss after a Windows 11 update.

Via Device Manager:

1. Right-click Start → Device Manager
2. Expand Sound, video and game controllers
3. Right-click your audio device (usually Realtek High Definition Audio or Intel Smart Sound Technology)
4. Click Update driver → Search automatically for drivers

Via manufacturer website (recommended):

• For Realtek drivers: go to your laptop or motherboard manufacturer’s support page and download the latest audio driver for your specific model
• For Intel Smart Sound Technology: visit intel.com/support and search for your processor model

Avoid generic driver update tools — always use the manufacturer’s official source.

Fix 5 – Uninstall and Reinstall the Audio Driver

Sometimes updating isn’t enough — the existing driver is too corrupted to update cleanly. A full reinstall fixes this.

1. Open Device Manager
2. Expand Sound, video and game controllers
3. Right-click your audio device → Uninstall device
4. Check Attempt to remove the driver for this device if the option appears
5. Click Uninstall
6. Restart your PC — Windows will automatically reinstall a basic driver on boot
7. Test sound, then install the latest driver from the manufacturer’s website for full functionality

Fix 6 – Check That Audio Services Are Set to Automatic

If the Windows Audio service is set to start manually instead of automatically, it won’t launch at boot — leaving you with no sound until you start it manually.

1. Press Windows + R, type services.msc, press Enter
2. Find Windows Audio → double-click it
3. Set Startup type to Automatic
4. Click Start if the service isn’t running
5. Click Apply → OK
6. Repeat for Windows Audio Endpoint Builder
7. Restart your PC

Fix 7 – Run SFC and DISM

Corrupted Windows system files can break audio functionality at a deeper level than a driver reinstall can fix.

Open Command Prompt as administrator and run:

sfc /scannow

Wait for it to complete, then run:

DISM /Online /Cleanup-Image /RestoreHealth

Restart your PC after both complete. Then run sfc /scannow once more to catch anything DISM repaired.

Part 2 – Crackling, Popping, or Static Sound

Fix 1 – Change the Audio Sample Rate and Bit Depth

Mismatched audio sample rates between the driver and Windows are a very common cause of crackling and popping sounds.

1. Right-click the speaker icon → Sound settings
2. Scroll down and click More sound settings
3. In the Playback tab, right-click your default device → Properties
4. Go to the Advanced tab
5. Under Default Format, try different combinations:
   • 16 bit, 44100 Hz (CD Quality)
   • 24 bit, 48000 Hz
   • 24 bit, 44100 Hz
6. Click Test after each change to hear whether the crackling stops
7. Click Apply when you find one that works

Fix 2 – Disable Audio Enhancements

Windows applies audio processing effects by default — bass boost, virtual surround, loudness equalization. These enhancements can cause crackling, especially on lower-end hardware.

1. Right-click the speaker icon → Sound settings → More sound settings
2. Right-click your playback device → Properties
3. Go to the Enhancements tab (or Advanced tab on some systems)
4. Check Disable all enhancements (or turn off each enhancement individually)
5. Click Apply → OK
6. Test playback

Fix 3 – Disable Exclusive Mode

Exclusive mode lets applications take direct control of the audio device, bypassing Windows audio mixing. This can cause crackling when multiple apps compete for audio control.

1. Right-click the speaker icon → Sound settings → More sound settings
2. Right-click your playback device → Properties
3. Go to the Advanced tab
4. Uncheck Allow applications to take exclusive control of this device
5. Click Apply → OK

Fix 4 – Change the Power Plan

Windows power-saving settings can throttle the audio device to reduce power consumption — causing stuttering and crackling, especially on laptops.

1. Open Control Panel → Hardware and Sound → Power Options
2. Select High performance (or Balanced if High performance isn’t available)
3. Click Change plan settings → Change advanced power settings
4. Expand Multimedia settings → When playing video
5. Set it to Optimize video quality
6. Click Apply → OK

Also check:

• Expand PCI Express → Link State Power Management → set to Off
• This prevents the system from throttling PCI audio devices

Fix 5 – Update or Roll Back the Audio Driver

A recent driver update can introduce crackling that wasn’t there before. If the crackling started after a driver update, roll it back.

To roll back:

1. Open Device Manager → Sound, video and game controllers
2. Right-click your audio device → Properties
3. Go to the Driver tab → click Roll Back Driver

To update (if the crackling is on an older driver): Download the latest driver directly from your manufacturer’s support page.

Fix 6 – Check for USB or Bluetooth Interference

If you’re using USB speakers, a USB hub, or Bluetooth audio, interference from nearby devices can cause crackling.

• Try plugging USB speakers or headphones directly into the PC (not through a hub)
• Move Bluetooth devices closer to the PC and away from other wireless devices (routers, microwaves, other Bluetooth devices)
• Try a different USB port — some ports on the same controller share bandwidth

Part 3 – Headphone Not Detected When Plugged In

Fix 1 – Manually Set Headphones as Output Device

Windows 11 doesn’t always switch automatically when you plug in headphones. Force it manually.

1. Right-click the speaker icon → Sound settings
2. Under Output, click the dropdown
3. Select your headphones from the list
4. If they don’t appear — continue with the fixes below

Fix 2 – Check the Realtek Audio Console

If your PC uses Realtek audio (most laptops and desktop motherboards do), the Realtek Audio Console controls what happens when you plug something into the headphone jack.

1. Search Realtek Audio Console in the Start menu and open it
2. Click Device advanced settings
3. Under Connector Settings, make sure Headphones or Front Panel Jack Detection is enabled
4. Also check the jack retasking settings — make sure the front jack is set to Headphone Output, not Line Out or Microphone

If Realtek Audio Console isn’t installed, download it from the Microsoft Store — search “Realtek Audio Console” directly.

Fix 3 – Enable Jack Detection in Sound Settings

1. Right-click the speaker icon → Sound settings → More sound settings
2. Go to the Playback tab
3. Right-click anywhere in the empty area → check Show Disabled Devices and Show Disconnected Devices
4. If your headphones appear grayed out, right-click them → Enable
5. Right-click them again → Set as Default Device

Fix 4 – Check the Headphone Jack Physically

This sounds obvious, but it’s worth verifying:

• Try the headphones on a different device to confirm they work
• Try a different pair of headphones in the same jack
• Check the jack for dust, lint, or debris — use a can of compressed air to clean it
• Try plugging in slowly and firmly — some jacks require a full click to make contact

If headphones work on another device but not on your PC at all, the jack itself may be faulty — in which case a USB audio adapter is a quick and affordable workaround.

Fix 5 – Update the Audio Driver for Jack Detection

Headphone detection specifically relies on the audio driver’s jack-sensing capability. If the driver is outdated, it may not recognize the plug event.

1. Go to your laptop or motherboard manufacturer’s support page
2. Find the audio driver for your exact model
3. Download and install it
4. Restart your PC and plug in the headphones again

Generic drivers from Windows Update often lack jack detection support — always use the manufacturer’s driver for this specific issue.

Fix 6 – Check for a Conflicting IDT or VIA Audio Driver

Some systems have multiple audio drivers installed simultaneously — which can prevent jack detection from working properly.

1. Open Device Manager → Sound, video and game controllers
2. Look for more than one audio device listed (e.g., both Realtek and IDT High Definition Audio)
3. If you see a device you don’t use, right-click → Disable device
4. Test headphone detection again

FAQ

Q: Why did my audio stop working after a Windows 11 update? Windows updates sometimes reset audio settings or replace your manufacturer’s driver with a generic one. Check your default output device first, then reinstall the manufacturer’s audio driver. This fixes the problem in most post-update cases.

Q: My sound works through HDMI but not my speakers. What’s wrong? Windows switched your default output to the HDMI display. Click the speaker icon in the taskbar, open the output device dropdown, and select your speakers manually. Then right-click and set them as the default device in Sound settings.

Q: Why does my audio crackle only when the laptop is unplugged? This is a power management issue. Windows reduces power to audio hardware when running on battery. Change your power plan to Balanced or High Performance, and disable Link State Power Management for PCI Express in the advanced power settings.

Q: My headphones work on my phone but not my Windows 11 PC. Why? The headphone jack may not be detecting the plug, or the device isn’t being set as the output automatically. Check the Realtek Audio Console for jack detection settings, and manually set the headphones as your default output device in Sound settings.

Q: How do I know if my audio problem is hardware or software? Boot into a live Linux USB (like Ubuntu). If audio works fine in Linux, the problem is Windows software or drivers. If it doesn’t work in Linux either, the hardware itself is likely at fault.

Q: Can a Windows 11 update corrupt audio drivers? Yes. Windows Update can replace manufacturer-specific audio drivers with generic ones that lack features or have bugs. Always download audio drivers directly from your PC or motherboard manufacturer’s website rather than relying on Windows Update.

Q: My microphone stopped working at the same time as my headphones weren’t detected. Are they related? Yes — both are controlled by the same audio driver and jack detection system. Fix the headphone detection issue first (Realtek Audio Console, driver reinstall), and the microphone issue usually resolves at the same time.

Q: Is it safe to uninstall my audio driver? Yes. Windows will automatically reinstall a basic driver on the next boot, so you won’t be left without any audio capability. Uninstalling and reinstalling is a standard and safe troubleshooting step.

Final Thoughts

Audio problems on Windows 11 look intimidating because there are so many possible causes — but they almost always come down to three things: the wrong output device being selected, a driver that’s outdated or corrupted, or a settings conflict like sample rate or power management.

Work through the fixes in order for your specific problem. Most cases are resolved by Fix 1 or Fix 2 in each section. If you reach the SFC and driver reinstall steps without a fix, the in-place Windows repair or a clean driver install will almost certainly resolve it.

Your audio will be back to normal faster than you think.
