SOLVED: Windows Randomly Changing Volume

Are you noticing your Windows PC’s volume fluctuating on its own, getting louder or quieter without any user input? This issue can be frustrating, especially during meetings, gaming, or video playback. Fortunately, this behavior is fixable.

We will walk you through why Windows randomly changes volume and how to stop it on Windows 10 and 11 using effective troubleshooting methods.

Why Is Windows Automatically Changing Volume?

Volume issues can be caused by a mix of software and system settings. Here are the most common culprits:

• Audio enhancements or communications settings
  
• Malfunctioning drivers or outdated sound software
  
• Third-party apps overriding system settings
  
• Malware affecting audio behavior
  
• Corrupted system files or user profiles
  

Understanding the cause helps target the right solution quickly.

How to Fix Windows Randomly Changing Volume

Fix 1: Disable Automatic Volume Adjustments

Windows adjusts volume during calls by default. This setting may interfere with normal playback.

For Windows 10/11:

1. Right-click the speaker icon in the taskbar > select Sounds
   
2. Navigate to the Communications tab
   
3. Choose “Do nothing”
   
4. Click Apply > OK
   

This prevents Windows from automatically lowering or raising volume during audio input/output events.

Fix 2: Disable Audio Enhancements

Audio enhancements are designed to improve sound quality but may cause unexpected changes.

Here’s how to disable them:

1. Press Windows + R, type mmsys.cpl, and press Enter
   
2. Under the Playback tab, select your active audio device
   
3. Click Properties
   
4. Go to the Advanced tab
   
5. Check “Disable all enhancements”
   
6. Click Apply > OK

Fix 3: Update or Reinstall Audio Drivers

Outdated or buggy drivers can lead to fluctuating audio levels. Updating or reinstalling outdated drivers can fix the issue. Here’s how to do it.

To update audio drivers:

1. Press Windows + X and select Device Manager
   
2. Expand Sound, video, and game controllers
   
3. Right-click your audio driver > choose Update driver
   
4. Select Search automatically for drivers
   

If the issue continues, uninstall the driver and restart your PC. Windows will reinstall it automatically.

Fix 4: Check App-Specific Volume Levels

Some apps, like Discord or Spotify, have independent volume controls. These may conflict with system settings.

To check per-app volumes:

1. Right-click the speaker icon > Open Volume Mixer
   
2. Ensure no app is unusually loud or quiet
   
3. Adjust individual sliders as needed

Fix 5: Run the Audio Troubleshooter

Built-in troubleshooters can automatically detect and fix audio issues.

Steps:

1. Go to Settings > System > Sound
   
2. Scroll down to Advanced > select Output device
   
3. Click Troubleshoot and follow the prompts

Fix 6: Scan for Malware Interference

Malware may cause system behavior changes, including audio anomalies.

Use Windows Security:

1. Go to Settings > Update & Security > Windows Security
   
2. Click Virus & threat protection
   
3. Choose Quick scan or Full scan
   

However, built-in protection may miss advanced threats. That’s where third-party tools come in.

1. Go to Settings > Accounts > Family & other users
   
2. Click Add someone else to this PC
