Windows 10 is an impressive operating system, offering a user-friendly interface and a plethora of features. However, like any system, it can encounter issues. One common problem users face is the lack of sound after the computer wakes up from sleep mode. This issue can be frustrating, especially if you rely on audio for gaming, video calls, or streaming media. Fortunately, there are several methods to troubleshoot and resolve the no sound problem after sleep mode in Windows 10.
In this article, we will guide you through the common causes of this issue and provide step-by-step solutions to restore sound functionality.
Understanding the Problem
Before diving into solutions, let’s understand the potential causes behind the no sound issue after sleep mode. When a computer goes into sleep mode, it essentially enters a low-power state, pausing operations to conserve energy. However, this transition might disrupt audio drivers or settings, leading to sound problems.
Some common reasons for no sound after sleep mode include:
-
Outdated or Corrupted Audio Drivers: Audio drivers manage communication between the operating system and audio hardware. If they become outdated or corrupted, they may fail to function properly after waking up from sleep.
-
Power Management Settings: Windows has power management features that can disable devices like sound cards to save energy. Sometimes, these settings may cause audio devices to not reactivate correctly after sleep.
-
Conflicting Applications: Certain applications might interfere with audio services or settings, especially if they’re configured to manage audio devices.
-
Windows Updates: Occasionally, updates to the operating system can lead to unexpected behavior in system components, including audio.
With these potential causes in mind, let’s explore actionable solutions to restore sound after your Windows 10 machine wakes from sleep.
Step 1: Check the Basics
Before delving into technical fixes, it’s wise to start with the basics. Sometimes, the solution can be as simple as checking if the volume is muted or if the correct audio output is selected.
-
Check Volume Levels:
- Click on the speaker icon in the system tray (bottom right corner).
- Ensure the volume slider is turned up and not muted. If the icon shows a muted symbol, click on it to unmute.
-
Verify Audio Output Device:
- Right-click on the speaker icon and select “Playback devices.”
- Check if the correct audio output device is selected and set as the default. If you see multiple devices, right-click on the one you want to use (like "Speakers" or "Headphones") and choose “Set as Default Device.”
-
Restart Your Computer:
- Sometimes, all it takes is a good old restart to refresh system settings and restore functionality.
Step 2: Update Audio Drivers
If checking the basics doesn’t resolve the sound issue, the next step is to update your audio drivers. Windows 10 usually updates drivers automatically, but sometimes manual updates are necessary.
-
Open Device Manager:

-
Locate Sound Drivers:
- Expand the “Sound, video and game controllers” section.
- Right-click on your audio device (like Realtek High Definition Audio) and select “Update driver.”
-
Search Automatically for Drivers:
- Choose “Search automatically for updated driver software.” Windows will search for the latest drivers and install them if available.
-
Restart Your Computer:
- Restart your PC to apply any changes.
If Windows doesn’t find a new driver, you can also visit the manufacturer’s website to download the latest drivers manually.
Step 3: Adjust Power Management Settings
Another culprit behind the no sound issue after sleep could be power management settings affecting your audio device. Here’s how to adjust those settings:
-
Access Device Manager:
- Right-click the Start button and select “Device Manager.”

Step 5: Check for Windows Updates
Keeping your system updated is vital not only for security but also for functionality. Sometimes, the no sound issue can be resolved with the latest Windows updates.
-
Access Windows Update Settings:
- Go to Settings → Update & Security → Windows Update.
-
Check for Updates:
- Click on “Check for updates” and allow Windows to search for any available updates. Install them if found.
-
Restart Your Computer:

Step 6: Reinstall Audio Drivers
If the previous steps haven’t yielded results, reinstalling audio drivers can often resolve lingering issues.
-
Open Device Manager:
- Right-click on the Start button and select “Device Manager.”
-
Uninstall Audio Drivers:
- Expand “Sound, video and game controllers,” right-click your audio device, and choose “Uninstall device.”
-
Reboot Your Computer:
- Windows will attempt to reinstall the driver automatically upon restart.
Step 7: Modify Registry Settings
For advanced users, tweaking registry settings can sometimes help fix sound issues. However, it’s essential to back up the registry before making any changes, as incorrect modifications can lead to system problems.
-
Open the Registry Editor:
- Press
Win + R, typeregedit, and press Enter.
- Press
-
Navigate to the Following Path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AudioEndpointBuilder -

-
Repeat for the Following Path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Audiosrv -
Reboot Your Computer:
- After making these changes, a system restart is necessary.
Step 8: Additional Fixes
In some cases, users may find other workarounds that help restore sound functionality. Here are a few suggestions:
-
Disable Audio Enhancements: Sometimes audio enhancements can interfere with sound. Right-click on the volume icon, select "Playback devices," choose your default device, go to "Properties," and then to the "Enhancements" tab to disable them.
-
Try Different Audio Formats: Under the "Advanced" tab in the audio device's properties, experiment with different audio formats.
