• Sound is very quiet or muffled
• Audio crackling, popping, or distorted
• Sound only plays from one speaker (left or right)
• Audio delays or lag

Step 2. Make sure the volume isn't muted (no red X on the speaker icon) and the volume slider is above 0.

Step 3. Click the arrow next to the volume slider to see available output devices.

Step 4. Select the correct device (e.g., "Speakers (Realtek Audio)" or "Headphones").

Step 5. If you're using external speakers or headphones, make sure they're properly connected and powered on.

Fix 2: Run the Audio Troubleshooter

Windows 11 has a built-in audio troubleshooter that can automatically detect and fix common sound issues.

Step 1. Press Win + I to open Settings.

Step 2. Go to "System" > "Troubleshoot" > "Other troubleshooters".

Step 3. Find "Recording Audio" or "Playing Audio" and click "Run".

Step 5. After it completes, check if sound works.

If you have multiple audio devices, Windows might be sending sound to the wrong one. Set the correct device as default.

Step 1. Press Win + R, type mmsys.cpl, and press Enter.

Step 2. In the "Playback" tab, find your speakers or headphones.

Step 3. Right-click your preferred device and select "Set as Default Device".

Fix 4: Update or Reinstall Audio Drivers

Outdated or corrupted audio drivers are the most common cause of no sound issues. Updating or reinstalling them usually fixes the problem.

Update Audio Drivers

Step 1. Press Win + X and select "Device Manager".

Step 3. Right-click your audio device (e.g., "Realtek Audio" or "High Definition Audio Device") and select "Update driver".

Step 4. Choose "Search automatically for drivers" and follow the prompts.

Reinstall Audio Drivers

Step 2. Right-click your audio device and select "Uninstall device".

Step 3. Check "Attempt to remove the driver for this device" if available.

Step 3. Right-click your audio device and select "Properties".

Step 4. Go to the "Driver" tab.

FAQs About Windows 11 Sound Issues

Why is there no sound on my Windows 11?

Common causes include muted volume, incorrect output device selected, outdated or corrupted audio drivers, or the Windows Audio service being disabled. Check the volume first, then try running the audio troubleshooter.

How do I fix "No audio output device is installed"?

This usually means the audio driver is missing or corrupted. Open Device Manager, expand "Sound, video and game controllers", and check if your audio device is listed. If it has a yellow exclamation mark, update or reinstall the driver.

Why does my Windows 11 sound crackle?

Audio crackling or popping is often caused by outdated drivers, audio enhancements, or high CPU/DPC latency. Update your audio drivers, disable audio enhancements (Fix 6), and close unnecessary background apps.

Why is my Bluetooth audio not working in Windows 11?

Make sure the Bluetooth headphones are connected and set as the default playback device. Go to Settings > Bluetooth & devices, remove the device, and re-pair it. Also check that the Bluetooth service is running.

How do I restart the Windows Audio service?

Press Win + R, type services.msc, find "Windows Audio", right-click and select "Restart". Also make sure "Windows Audio Endpoint Builder" is running.

Back Up and Restore Windows with Qiling Disk Master

Before you reinstall the audio driver, restart Windows Audio services, or switch to a generic driver, create a full system backup. A system image means you can undo every driver and service change in minutes if the sound gets worse instead of better. Qiling Disk Master handles both the backup and the restore.

Part 1: Create a Full System Backup

Step 1. Install and open Qiling Disk Master. On the home screen, open "Backup and Recovery" and choose "System Backup". This option automatically includes Windows and the hidden boot partitions, so you do not have to select them one by one.

Step 2. Check the source. The disk where Windows is installed and its system partitions are already ticked for you. If you only need your personal documents, run a separate "File Backup" task instead.

Step 3. Click the destination box and choose where the image should be saved. Use an external HDD or SSD, a NAS, or any drive other than the one you are about to repair, and make sure it has enough free space.

Step 4. Review the task summary and click "Proceed". Wait until the progress bar reaches 100%. Do not unplug the drive or turn off the PC while the backup is running.

Part 2: Restore Windows from the Backup

Step 1. Open Qiling Disk Master again, go to "Backup and Recovery", and select the recovery option. Your backup images are listed, so pick the one you created before the repair.

Step 2. Choose the target disk or partition. Normally you restore to the original system disk. If the drive was replaced, select the new disk instead, and the restore rebuilds Windows together with its boot partitions.

Step 3. Preview the restore plan, click "Proceed", and confirm the warning. The PC restarts to finish the job, and Windows comes back exactly as it was on the day the image was created.

Conclusion

Windows 11 no sound is usually fixable by checking the volume and output device, running the audio troubleshooter, or updating the audio drivers. If the issue persists, restart the Windows Audio service, disable audio enhancements, or roll back the driver. For most users, one of these fixes will resolve the issue.
