Fix Sound Fading In and Out in Windows 11

When sound fades in and out, your computer’s audio output becomes inconsistent. You might notice that the volume drops suddenly, returns to normal after a few seconds, or gradually becomes quieter before getting louder again.

For example, you might be watching a YouTube video, and the speaker volume suddenly drops even though the Windows volume slider remains at 80%. Sometimes, the same problem occurs when using headphones, external speakers, or Bluetooth audio devices.

Some common reasons behind this issue include:

Incorrect communication settings: Windows may automatically reduce the volume of other sounds when it detects communication activity.

Audio enhancements: Certain sound-processing effects can interfere with normal audio playback.

Outdated audio drivers: Old, corrupted, or incompatible drivers can cause unexpected sound problems.

Bluetooth connectivity: Wireless interference, low battery levels, or connection problems can interrupt audio playback.

Application-specific settings: Some applications have their own volume controls and automatic audio adjustment features.

Now, let’s look at the solutions.

How to Fix Sound Fading In and Out in Windows 11

To fix sound fading in and out in Windows 11, disable automatic volume reduction in Communication settings, turn off audio enhancements, run the Windows audio troubleshooter, update your sound drivers, and check your speaker or headphone connections. 

If the problem continues, restart Windows Audio services and check application-specific volume settings.

1: Disable Automatic Volume Adjustment in Communication Settings

One of the first things you should check is the Windows Communications setting.

Windows 11 can automatically reduce the volume of other sounds when it detects that you’re using your computer for communication. For example, when you’re attending a voice or video call, Windows might lower the volume of background music or other applications.

Sometimes, this behavior can make it seem like your sound is fading in and out.

Here’s how to disable it.

1. Press Windows + R on your keyboard to open the Run dialog box.
2. Type mmsys.cpl and press Enter.
3. When the Sound window opens, select the Communications tab.
4. You’ll see several options under the heading “When Windows detects communications activity.”
5. Select Do nothing.
6. Click Apply, followed by OK.

This prevents Windows from automatically lowering the volume of other sounds when communication activity is detected.

Now, play some music or a video and check whether the problem is resolved.

2: Turn Off Audio Enhancements

Windows 11 includes audio enhancement features designed to improve sound quality. Depending on your audio hardware and drivers, these enhancements can sometimes cause unexpected volume changes.

Disabling them is worth trying, especially if your audio keeps getting louder and quieter without any apparent reason.

Follow these instructions.

1. Press Windows + I to open Settings.
2. Select System from the left sidebar.
3. Click Sound.
4. Under the Output section, select the speaker or headphone device you’re currently using.
5. Scroll down and locate the Audio enhancements option.
6. Click its dropdown menu and select Off, if available.

After disabling audio enhancements, play an audio file or stream a video.

If the sound remains consistent, one of the audio effects was likely interfering with playback.

3: Run the Windows Audio Troubleshooter

Not sure what’s causing the problem? Let Windows check your audio configuration.

Windows 11 includes an audio troubleshooter that can identify common sound-related problems and suggest or apply automatic fixes.

Here’s how to run it.

1. Open Settings by pressing Windows + I.
2. Click System.
3. Select Troubleshoot.
4. Click Other troubleshooters.
5. Find the Audio troubleshooter.
6. Click the Run button next to it.
7. Follow the instructions displayed on your screen.

Windows will check your audio devices, sound configuration, and related services for common problems.

If it finds an issue, follow the recommended instructions to fix it.

Note: Depending on your Windows 11 version, the troubleshooter might direct you to the Get Help app instead of displaying the older troubleshooting interface.

4: Update Your Audio Drivers

An outdated or corrupted audio driver can cause several sound-related problems, including crackling, distorted audio, sudden volume changes, and sound fading in and out.

Updating your audio driver can help resolve compatibility issues between Windows 11 and your sound hardware.

Follow these steps.

1. Right-click the Start button.
2. Select Device Manager.
3. Expand the Sound, video and game controllers section.
4. Find your audio device, such as Realtek Audio or another manufacturer-specific device.
5. Right-click the device and select Update driver.
6. Choose Search automatically for drivers.
7. Follow any instructions provided by Windows.

If Windows finds an available driver, install it and restart your computer.

You can also visit your computer manufacturer’s official website to download the latest compatible audio driver.

For example, if you’re using an HP, Dell, Lenovo, or ASUS computer, check its official support page for the appropriate audio driver.

Avoid downloading drivers from unknown websites.

5: Check the Volume Mixer

Sometimes, the problem isn’t with your speakers or audio driver. Instead, an individual application might be changing its volume independently.

Windows 11 includes a Volume Mixer that allows you to control the audio level of different applications.

Here’s how to check it.

1. Right-click the speaker icon on the taskbar.
2. Select Open volume mixer.
3. Look under the Apps section.
4. Find the application where you’re experiencing the audio problem.
5. Check whether its volume level is unusually low.
6. Adjust the application volume and make sure it isn’t muted.

For example, if YouTube sounds quieter than other applications, check your browser’s volume level in the Volume Mixer.

Also, check the volume slider inside the application itself.

6: Restart Windows Audio Services

Windows relies on background services to manage sound playback. If these services aren’t working correctly, you might experience unexpected audio behavior.

Restarting the Windows Audio services can help resolve temporary sound-related problems.

Here’s what you need to do.

1. Press Windows + R.
2. Type services.msc and press Enter.
3. Find Windows Audio in the Services window.
4. Right-click it and select Restart.
5. Find Windows Audio Endpoint Builder.
6. Right-click it and select Restart, if available.
7. Close the Services window and test your audio.

If Windows asks you to restart related services, allow it to do so.

This process refreshes the audio services without requiring you to reinstall Windows or reset your computer.

7: Check Your Bluetooth Headphones or Speakers

Are you using wireless headphones or Bluetooth speakers? If so, your connection might be responsible for the inconsistent audio.

Bluetooth audio can become unstable because of wireless interference, low battery levels, outdated drivers, or connection problems.

To troubleshoot it, first make sure your headphones or speakers have sufficient battery power.

Next, move closer to your computer and temporarily disconnect other Bluetooth devices that you don’t need.

You can also reconnect your audio device.

1. Open Settings.
2. Select Bluetooth & devices.
3. Find your headphones or speaker.
4. Click the three-dot menu next to the device.
5. Select Remove device.
6. Confirm the removal.
7. Put your headphones or speaker into pairing mode.
8. Click Add device, select Bluetooth, and reconnect your device.

Once connected, play some audio and check whether the fading issue has disappeared.

If you’re using wired headphones, check the cable, audio jack, and connection. A loose or damaged cable can also cause inconsistent sound.

8: Disable Exclusive Mode

Some applications can take exclusive control of an audio device. This may interfere with other applications trying to play sound simultaneously.

Disabling Exclusive Mode can help if your audio becomes inconsistent when switching between applications.

Follow these steps.

1. Press Windows + R.
2. Type mmsys.cpl and press Enter.
3. Select the Playback tab.
4. Double-click your active speaker or headphone device.
5. Open the Advanced tab.
6. Under Exclusive Mode, uncheck Allow applications to take exclusive control of this device.
7. Click Apply and then OK.

Restart the application you’re using and test the sound again.

Keep in mind that some specialized audio applications work best with Exclusive Mode enabled. If disabling it creates another problem, restore the original setting.

9: Install Pending Windows Updates

Microsoft regularly releases Windows updates that include security improvements, bug fixes, and hardware compatibility updates.

If your sound started fading after a recent system change, installing available updates might help.

1. Press Windows + I.
2. Select Windows Update from the left sidebar.
3. Click Check for updates.
4. Allow Windows to search for available updates.
5. Install any relevant updates.
6. Restart your computer if required.

You can also check Advanced options > Optional updates > Driver updates for compatible audio drivers.

Only install drivers that are appropriate for your hardware.
