Fix Audio Cracking After Waking from Sleep Mode
- 6 ways to do it
- Needs administrator rights
- Includes a restart or sign-out

Audio cracking after waking from sleep is a distortion problem. You hear static, popping or buzzing when your sound card or USB speakers fail to resume properly from a low-power state. It happens on Windows 10 and Windows 11 PCs, usually because the audio driver or the USB port loses its state during the wake-up process.
You can fix it without rebooting every time you step away from your desk. The fixes below go from the quickest and safest to the more advanced. Work through them in order and test your sound after each one, so you know which change actually helped.
Fix audio cracking after waking from sleep mode by restarting the background sound program. Press the Win, type Services, and open the Services app. Scroll down the list, right-click on Windows Audio, and select Restart. This refreshes your sound system without needing to reboot your entire computer.
Basic Checks and Quick Fixes
These fixes take a few seconds each and change no advanced settings. Unplugging and re-plugging your USB or Bluetooth audio device forces Windows to reload the connection and clear the static. Restarting the Windows Audio service refreshes the background sound processes. Try them first, and use them as a stopgap if the permanent fixes later in this guide don’t fully solve the problem.
Unplug and re-plug your audio device
- Unplug your USB speakers, USB headset or Bluetooth headphones. For Bluetooth, you can instead remove the device from Settings Bluetooth & devices and pair it again.
- Wait five seconds.
- Plug the device back in. Windows should recognize it again, usually with a short chime.
- Play some audio. If the static was caused by a bad wake-up, it should be gone.
Restart the Windows Audio service
Windows runs background programs called services to handle everyday tasks, and one of them manages sound. You can restart it without rebooting. You need an administrator account for this.
- Press the Windows key, type Services, and click the Services app. The Services window opens with an alphabetical list.
- Scroll down to Windows Audio.
- Right-click Windows Audio and select Restart.
- If a box asks whether you also want to restart related services, click Yes.
- Wait a few seconds for the status to refresh, then play some audio. Sound may drop out for a moment while the service restarts.
Disconnect USB hubs
Many cheap USB hubs struggle to manage power correctly when a computer wakes from sleep. If your audio device plugs into a hub, a monitor’s built-in USB ports or a keyboard pass-through port, those are the first suspects.
- Unplug the audio device from the hub.
- Plug it directly into a USB port on the back or side of your computer. On a desktop, the ports on the back of the case, connected straight to the motherboard, are usually the most reliable.
- Put the PC to sleep, wake it, and listen for the crackling.
Method 1Restart Your Audio Driver
Disabling and re-enabling your audio device in Device Manager refreshes the connection between Windows and your sound card. It resets the sound software without deleting or reinstalling any files, so it is safe to try. It is also a good manual workaround to use after a wake-up when the crackling appears. You need administrator rights for this.
- Right-click the Start button on your taskbar and select Device Manager. The Device Manager window opens.
- Scroll down the list and click the arrow next to Sound, video and game controllers to expand it.
- Find your main audio device. It is usually called Realtek Audio, Intel High Definition Audio, or something similar. For USB speakers or a headset, the device may have its own name here.
- Right-click your audio device and select Disable device. A warning may tell you the device will stop working.
- Click Yes to confirm. The device icon will show a small down arrow, and your sound will stop.
- Wait about five seconds.
- Right-click the same audio device again and select Enable device.
- Play some audio to see if the crackling is gone.

Method 2Update or Roll Back Your Audio Drivers
Outdated or buggy audio drivers are a common cause of post-sleep glitches. Hardware manufacturers often release driver versions that fix sleep-mode bugs and popping noises. The opposite can also happen: a new driver introduces the problem. So there are two options, update the driver or roll it back, depending on whether the crackling started after an update.
Update the driver
- Right-click the Start button and select Device Manager.
- Expand Sound, video and game controllers.
- Right-click your audio device and select Update driver.
- Choose Search automatically for drivers. Windows searches your computer and the internet for a newer version.
- If it finds one, follow the on-screen steps to install it, then restart your computer.
If Windows says the best driver is already installed, that only means Windows has nothing newer in its own catalog. The manufacturer’s website for your PC, laptop or motherboard may still have a newer audio driver, so it is worth checking there.
If the noise started right after a driver update, the new driver may be unstable. Rolling back restores the version you had before.
- Open Device Manager and expand Sound, video and game controllers.
- Right-click your audio device and select Properties.
- Click the Driver tab at the top of the window.
- Click the Roll Back Driver button. If it is greyed out, Windows has no earlier version stored, and you can’t roll back from here.
- Choose a reason when asked, click Yes, and follow the prompts to restore the previous version.
- Restart your computer, then put the PC to sleep and wake it to test.
Method 3Disable Audio Enhancements
Audio enhancements are extra sound effects that Windows or your audio driver applies to the signal, such as bass boost, loudness equalization or virtual surround. They add processing, and after a sleep cycle they can conflict with the audio hardware and cause static. Turning them off often clears persistent cracking and popping. The steps below use the classic Control Panel sound window, which still works in Windows 11.
- Click the Start button, type Control Panel, and open the app.
- Click Hardware and Sound, then click Sound. A window opens showing your playback devices.
- Click your default speakers or headphones so they are highlighted, then click the Properties button at the bottom right.
- In the Properties window, look for a tab labeled Enhancements or Spatial sound. Depending on your driver and Windows version, the option may instead sit under the Advanced or General tab.
- Check the box that says Disable all enhancements or Disable all sound effects. On some drivers the option is an Enable audio enhancements box on the Advanced tab, and you uncheck it instead.
- Click Apply, then click OK.
- Repeat these steps for any other playback devices you use.
If you can’t find the setting here, in Windows 11 you can also open Settings System Sound, select your device, and set Audio enhancements to Off. To undo the change, reverse the checkbox or dropdown. If the crackling stays, you can turn the effects back on.

Method 4Change Audio Sample Rate and Bit Depth
The default format is the sample rate and bit depth Windows uses to send audio to your device. A format that is too demanding for your sound card or USB device can cause static as it comes out of sleep. Lowering the format gives the hardware an easier job. You can change it safely in the classic Control Panel sound window, and you can change it back at any time.
- Open the Control Panel and go to Hardware and Sound Sound.
- Select your primary speakers or headphones and click Properties.
- Click the Advanced tab at the top.
- Look for the Default Format section. The drop-down menu has options like 24-bit, 48000 Hz or 16-bit, 44100 Hz.
- Change the setting to a lower-quality format, such as 24-bit, 44100 Hz or 16-bit, 48000 Hz. Available options depend on your device, so you may see a different list.
- Click Test to hear a sample tone and check how it sounds.
- Click Apply, then OK.
- Put the PC to sleep and wake it to see whether the crackling returns. If it does, try another format from the list.
Method 5Adjust USB Power Management Settings
By default, Windows can switch off power to USB hubs to save energy. If your speakers or headset are on USB, they may wake up with unstable power, and that shows up as crackling. Turning off this power saving keeps the ports powered. You need administrator rights for this. On a laptop running on battery, the change may cost a little battery life.
- Right-click the Start button and select Device Manager.
- Scroll down and click the arrow next to Universal Serial Bus controllers to open the list.
- Look for items named USB Root Hub, USB Root Hub (USB 3.0) or Generic USB Hub.
- Right-click the first hub in the list and select Properties.
- Click the Power Management tab. If there is no such tab, that hub doesn’t offer the setting, so move on to the next one.
- Uncheck the box that says Allow the computer to turn off this device to save power.
- Click OK.
- Repeat this process for every USB Root Hub and Generic USB Hub listed in Device Manager.
To undo the change, repeat the steps and tick the box again.
Method 6Turn Off Fast Startup
Fast Startup is a Windows feature that saves part of the system state to disk when you shut down, so the PC boots quicker. Drivers can carry over stale state from one session to the next, which can cause hardware glitches, including audio crackling. Turning it off means a full, clean start every time. This works on both Home and Pro editions.
- Click the Start button, type Control Panel, and open it.
- Click Hardware and Sound, then click Power Options.
- On the left side of the window, click Choose what the power buttons do.
- Click Change settings that are currently unavailable near the top. Approve the User Account Control prompt if one appears. The options under Shutdown settings are now editable.
- Under Shutdown settings, uncheck Turn on fast startup (recommended). If this option doesn’t appear at all, hibernation is probably turned off on your PC, which means Fast Startup isn’t active anyway.
- Click the Save changes button at the bottom.
- Restart your computer once to apply the change.
Your PC may take a few seconds longer to start from a full shutdown. To undo the change, follow the same steps and tick the box again.
Advanced Expert Tips: Unique Angles Competitors Miss
Most online guides stop after driver reinstalls and power management tweaks. If your audio still crackles after trying everything above, you need to look at deeper system settings. Here are two advanced methods that most websites miss.
Advanced Tip 1: Adjusting PCI Express Link State Power Management
PCI Express Link State Power Management lets Windows reduce power to devices on the PCI Express bus, which can include an internal sound card. If the card doesn’t recover cleanly from that low-power state, you may hear crackling after waking. Turning the setting off keeps the link at full power. It is safe to change, but it can use slightly more power, which matters most on a laptop running on battery. This setting is stored per power plan, so change it in the plan you actually use.
- Click the Start button, type Control Panel, and open it.
- Go to Hardware and Sound Power Options.
- Next to your currently selected power plan, click Change plan settings.
- Click Change advanced power settings. A small Power Options window opens.
- Scroll down the list and click the plus sign next to PCI Express to expand the category.
- Click the plus sign next to Link State Power Management.
- On a laptop you will see two settings, On battery and Plugged in. On a desktop you will see just one.
- Click each drop-down menu and change the setting from Maximum power savings or Moderate power savings to Off.
- Click Apply, then click OK.
If you don’t see the PCI Express category, your PC’s firmware or power plan doesn’t expose it, and you can skip this fix. To undo it, set the option back to Moderate power savings.
Advanced Tip 2: Checking for DPC Latency Spikes
DPC latency is the delay in how Windows handles tasks that drivers hand off for processing. When a poorly written driver holds up those tasks, audio can’t be delivered on time, and you hear crackling. LatencyMon is a free third-party tool that measures these delays and names the drivers causing them. It doesn’t fix anything itself, but it shows you which driver to update or replace.
- Download LatencyMon from the developer’s own website, not from a third-party download site.
- Install and run LatencyMon on your computer.
- Put your computer into sleep mode for a few minutes, then wake it back up.
- Open LatencyMon and click the green Play button at the top to start monitoring. Starting it after the wake-up lets it capture the behavior you are trying to diagnose.
- Let it run for a minute or two while you play some audio.
- Check the main results tab. LatencyMon tells you whether your system is suitable for real-time audio and highlights the drivers with the highest latency. The Drivers tab gives a more detailed breakdown.
- If a specific driver is causing the problem, update or reinstall that driver. Get it from the PC or device manufacturer’s website where possible.
Summary
Audio cracking after waking from sleep comes from power management conflicts and driver communication failures. Start with the quick fixes, then check your audio drivers, adjust USB power settings, and turn off Fast Startup if needed. If it still crackles, change the advanced power options and use LatencyMon to find the driver at fault. Change one setting at a time and test after each, so you know which fix worked.
