If your volume goes down by itself, you cannot just blame a single thing and get away with it. Volume controls on Windows 10 PCs can change due to several reasons, a faulty volume rocker on the headset, third-party app conflicts, or an audio driver glitch being the most common ones. 

And since there is not a single go-to solution, you can use the Windows audio troubleshooter. Sometimes, doing so might fix some issues on its own. Although the built-in troubleshooter can be hit-and-miss, it is worth giving a shot. Also, you can try the “Disable Sound Effects and Audio Enhancement” or “Downgrade to Windows Generic Drivers” process for better results.

Solutions to Volume Going Down by Itself in Windows 10

At least eight different troubleshooting approaches can be adopted to eliminate the issue of auto-lessening of volume as detailed in the following.

1. Run Windows Audio Troubleshooter

Windows 10 comes with a dedicated audio troubleshooter. It offers you to find and fix audio-related issues automatically. And you can access it from settings easily. 

Let’s run the Windows audio troubleshooter.

Step 1

Pressing the “Windows key + I” simultaneously take you to the settings. Then, go to the Update and Security section.

Step 2

Open the Troubleshoot tab in the left pane. After that, scroll down and check if any troubleshooters are available in the right pane. If not, click on Additional troubleshooters.

Step 3

You will get the Playing Audio option in the additional troubleshooter window that appears. Then, click Run the troubleshooter to launch the Windows audio troubleshooter. It will immediately scan your system for potential audio issues.

Step 4

You may have connected multiple audio devices. In such circumstances, select the affected device only and go to the next step.

Now, pursue the on-screen instructions and apply any recommended fix. After that, connect your device and inquire whether the audio issues are resolved or not.

2. Disable Sound Effects and Audio Enhancement

Your Realtek audio driver comes along with added enhancement features that allow you to tweak the bass boost, headphone virtualization, and loudness equalization options.

However, these enhancements can motivate your system volume to switch without any user input. Yet, you can resolve such volume-related issues by disabling all enhancements.

Let’s disable audio enhancements.

Step 1

In the bottom right corner of the taskbar, look for the “Speaker icon”. If you right-click on the icon and select “Sounds”, it opens the “Sound window” for you. Then, expand the “Playback” tab.

Step 2

Now, it’s time to locate the affected device, such as the headset. Then right-click on it and select Properties. After that, open the “Enhancement” tab in the Properties window.

Here, click the “Disable all enhancements” box and press “Apply” to save the changes. In the end, restart or reboot your PC and check for any improvements.

3. Disable Automatic Communication Activity

While receiving or placing telephonic calls, Windows is configured to adjust the volume of different sounds by default. However, sometimes this handy feature misinterprets incoming audio connections and causes volume-related issues.

Only disabling the Communication activity can resolve such issues.

Step 1

Press the “Windows Key+ R” simultaneously to open the run. Now, type here “mmsys.cpl” and click ok. 

Step 2

When you click ok, it expands the Sound window. Here, open the “Communications” tab and select the “Do nothing” option. And check “Apply” and “Ok” to save the changes. 

4. Update Audio Device Drivers in Device Manager

Sometimes an outdated or defective audio device leads your system audio controls to malfunction. So, you can update it from the device manager to resolve audio-related issues. 

Let’s update the audio device driver.

Step 1

At first, press “Windows key + R” to open the run. And then, type “devmgmt.msc” and check “ok”. This process leads you to the “Device manager”.  

Step 2

Expand the “Sound, video, and game controllers” section in the device manager. It provides the list of installed audio devices on your system. 

Step 3

Now, right-click on the affected audio device and select “Update driver”. Choose the “Search automatically for the drivers” option, as it commands Windows to scan for available new drivers and install them automatically. 

5. Roll Back Your Audio Device Driver

Generally, driver updates to your device fix the bugs and improve performance. However, sometimes new updates can also bring new problems. In this circumstance, a rollback to an earlier version can fix audio-related issues. 

Step 1

At first, open the “Device manager” and expand the “Sound, video, and game controller” section by following the same procedure you did in the previous troubleshooting process. 

Step 2

Now, right-click on your device and choose “Properties”. Then, open the “Driver” tab and click on “Roll Back Driver”. After that, complete the rollback by following the on-screen instructions. 

6. Downgrade to Windows Generic Drivers 

Sometimes, installed Realtek drivers can cause your system audio controls to malfunction. In such a case, you need to downgrade to a generic Windows audio driver. Once you switch to a generic driver, Windows will remove additional audio enhancement features that are offered by Realtek.

Let’s downgrade to a generic Windows driver. 

Step 1

At first, open “Drive manager” and expand the “Sound, video, and game controllers” section. Then, right-click on your “Realtek audio device” and select “Update driver”.

Step 2

Now, choose “Browse my computer from the driver”. After that, select “Let me pick from a list of available drivers on my computer”.

Step 3

Choose “High Definition Audio Device” and go forward to the “Next” option. At last, click “Yes” to confirm the action to install the generic driver. After completing the installment, restart your PC and check if the issues persist. 

7. Reinstall Audio Device Drivers

You can fix any temporary glitches by reinstalling your sound drivers, as Windows will automatically reinstall the required drivers during restart. 

Let’s reinstall audio device drivers. 

Step 1

First, hold “Windows key + X” simultaneously for a few seconds. Then, go to “Device Manager” from the WinX menu. 

Step 2

Expand “Sounds, video, and game controllers” in the Device manager. Now, right-click on “Realtek High definition Audio” which extends a menu. And from here, select “Uninstall Device”.

 Step 3

Now, click “Uninstall” to confirm the action. Once complete the process, restart your PC. This process lets your Windows scan the system for missing drivers and install them automatically.

8. Perform a Clean Boot

When you fail to identify the applications that interfere and cause automatic audio change, you need to perform a “Clean Boot” that disables irrelevant applications at the startup and diagnoses software conflict. 

Step 1

Pressing the “Windows Key + R” opens the run for you. Now, type “MSConfig” and click ok there. 

Step 2

Now, select “Selective Startup” and go to “Services” from the top. After that, check the “Hide All Microsoft Services” and click “Disable All”. In the end, click “Apply” and “Ok” to save the changes.

Final Words

It feels disgusting when your audio device’s volume goes up and down automatically. But doing some small steps can eradicate these issues. First, make sure that you have not muted your sound system accidentally. If not, try other troubleshooting processes. Though it is not that tricky, be careful while resolving these issues.
