Volume up and down automatically in Windows 10

Some users have reported that their volume increases or decreases automatically over time without any manual adjustments.. Some affected users report that the issue only occurs when they have more than one window / tab that produces sound. Other users report that the volume randomly jumps to the 100% without an apparent trigger. In most cases, the volume mixer settings do not change even though the sound volume has clearly changed. The vast majority of reports have been confirmed to occur on Windows 10.

Increase / lower volume automatically in Windows 10

What is causing the problem “automatic volume adjustment” in Windows 10?

We investigated this particular issue by examining various user reports and repair strategies that have been used successfully to resolve this issue.. According to our research, several common culprits are known to trigger this strange behavior in Windows 10:

• Sound effects or immediate mode is causing this: Realtek audio drivers include some features that can cause this particular behavior. Most of the time. Realtek's immediate mode and some other sound effects can cause automatic volume adjustment to some extent. Several users in similar situations have reported that the problem was fixed after turning off the additional sound effects.

• The problem is caused by the Windows communications function: there is a windows feature that ends up creating this particular problem for many users. Although it is designed to automatically adjust the volume when using the PC for communication purposes, can sometimes detect false positives that will end up reducing the volume when you are not. In this case, change the default behavior to “Do nothing” will solve the problem.

• Windows audio driver is causing the problem: as many users have reported, Realtek's default driver will update over time, which will end up causing this particular problem on some machines. If this scenario is applicable, downloading to a generic Windows driver should solve the problem.

• Dolby Digital Plus is adjusting the volume: one of the few third party audio drivers known to cause this problem is Dolby Digital Plus. This happens due to an audio feature called a volume leveler.. Unfortunately, turning it off will keep the same behavior, so you will have to turn off Dolby Digital Plus completely to solve the problem.

• A physical trigger is going up / decrease the volume: volume keys stuck on the keyboard or a working USB mouse key are potential causes that could lead to this particular problem. Unplugging the connected devices or unlocking the stuck keys will solve the problem in this case.

If you are looking for ways to prevent Windows volume from adjusting automatically, This article will provide you with several troubleshooting steps. Then, you will discover a collection of methods that other users in a similar situation have used successfully to prevent this behavior from occurring.

Method 1: turn off sound effects and immediate mode

It turns out that various Realtek drivers are known to cause this particular problem. We have not been able to find an official explanation as to why this problem occurs, but it seems the most popular trigger is to play something with sound, stop it then play it again. For most affected users, this scenario will result in a volume change that is not recognized by the speaker volume meter.

Fortunately, Some affected users have reported that this strange behavior no longer occurs after they have accessed sound settings and turned off all sound effects + immediate mode. Here is a quick guide on how to do it:

1. Press the Windows key + R to open a Run dialog. Then write “mmsys.cpl” and hit Enter to open the sound window.

2. Go to the Playback tab, select the playback device you are having trouble with, right click on it and choose Properties.

3. On the Properties screen, go to the Upgrades tab and check the boss associated with Disable all upgrades (Disable all sound effects). Then press Apply to save the changes.

   Note: If your speaker setup / headphone includes immediate mode, disable it too.

4. Restart your computer and see if the problem is resolved on the next startup.

If you still notice that the sound volume tends to rise or fall over time, go to next method.

Method 2: disable automatic volume adjustment via the communications tab

It turns out that another possible culprit that could end up turning down the audio volume is a Windows feature that is designed to automatically adjust the volume when you use your PC to make or receive phone calls.. Although this feature is great when it works properly, we have seen many reports from users where Windows misinterprets incoming or outgoing communications and lowers the volume when not needed.

If this scenario is applicable to your current situation, You can solve the problem by going to the Communications tab of the Sound menu and modifying the default behavior to $ 0027 Do nothing $ 0027 when a new communication is detected.

This is how you do it:

1. Press the Windows key + R to open the Run dialog. Then type »mmsys.cpl» and press Enter to open the Sound screen.

2. Inside the Sound window, go to the Communications tab and set the Do nothing option to $ 0027 When Windows Detects Communications Activity $ 0027.

3. Click Apply to save the changes and then restart your computer to see if the problem is resolved.

If you still encounter the same strange behavior with the sound volume, go to next method.

Method 3: switch to a generic Windows driver

If none of the methods listed below have helped prevent the sound volume from adjusting automatically, you can probably start to blame the sound driver that is currently active. We have seen many reports confirming that the problem ended up being caused by a Realtek driver that Windows Update installed automatically.

If you are using a Realtek sound driver, you can probably solve this particular problem by downgrading your current sound driver to the generic Windows driver that is already stored on your system. Here's how to do it:

1. Press the Windows key + R to open the Run dialog. Later, scribe “devmgmt.msc” and hit Enter to open Device Manager.

2. Inside Device Manager, expand the Sound Drivers drop-down menu, video and games.

3. Right-click on the active audio device and select Update Driver (Update driver software).

4. In the first message, click Browse my computer for driver software.

5. Later, on the next screen, click Let me choose from a list of drivers available on my computer.

6. Then start by checking the box associated with Show compatible hardware. Later, select High Definition Audio Device from the list and click Next.

7. Click Yes on the warning message to install this driver over your current driver installation.

8. Restart the computer to save the changes and see if the volume problem is resolved on the next startup.

Method 4: Desactive Dolby Digital Plus Advanced Audio

If you are using Dolby Digital Plus compatible audio equipment, most likely the program behind it causes automatic volume changes. This happens due to an audio feature called Volume Leveler.. But, Unfortunately, disabling this effect will not solve the problem. Unfortunately, you will have to disable Dolby completely to avoid conflict with your playback device.

Several users in a similar situation have reported that the issue was resolved after they visited the sound menu and disabled Dolby Digital Plus entirely.. Here's how to do this:

1. Press the Windows key + R to open the Run dialog. Then type »mmsys.cpl» and press Enter to open the sound screen. Ongoing dialogue: mmsys.cpl

2. In the Sound menu, select the speakers that adjust automatically and choose Properties. Access the properties screen of the Dolby speakers

3. Later, go to the Dolby tab and click the Power button (near Dolby Digital Plus) to deactivate it. Disabling Dolby Digital Plus

4. Restart the computer and see if the automatic volume adjustment stops with the next system startup.

If you still have the same automatic volume adjustment problems, go to next method.

Method 5: deal with physical triggers

Now that we have investigated all the possible software culprits that could end up causing the problem, let's investigate to find a physical trigger. You would be surprised how many people have discovered that the problem is due to the mouse wheel or volume key getting stuck.

If you are using a USB mouse with a wheel that can be used to reduce the volume, a mechanical problem (the controller) can cause you to get stuck when lowering or raising volume. In this case, unplugging the mouse and restarting the laptop will probably solve the problem.

Another possible physical trigger is hitting a physical volume key (most keyboard models have volume keyboards). If you are using a monitor with speakers, a stuck key on the monitor could alter the sound volume.
