- Disabling automatic volume adjustment for calls in Windows prevents the system from reducing the sound when initiating calls.
- Removing audio enhancements and checking drivers (Realtek and generic) fixes many volume changes and loss of quality.
- Programs such as Discord, Razer Synapse, Armoury Crate, or Dolby can attenuate or modify the volume and should be configured carefully.
- If the usual solutions fail, it's advisable to use the troubleshooter, check for suspicious processes, and rule out malware.
It's one of the most annoying bugs we can encounter: when Windows lowers the volume when starting calls (in Teams, Discord, Skype, WhatsApp, Google Meetetc.). You join a meeting or a call with friends and suddenly the music almost dies or the sound becomes distorted. The worst part is that you've often tried all the usual troubleshooting steps and the problem persists.
First of all, stay calm. There are solutions. And almost all of them involve Windows settings, audio drivers, and the headphone software itself.By systematically examining all these layers, the culprit is usually found, even if at first it seems like an impossible mystery to solve.
Why does Windows lower the volume when starting calls?
Before we start exploring options, it's advisable understand what Windows is really doing When it detects you're on a call or video call, the system includes several well-intentioned features that adjust the sound so you can hear the other person better, but in practice, they can ruin the experience if you're using music, games, and chatting at the same time.
One of the keys lies in the so-called “communications activity”When the system thinks you're on a call (for example, with Teams, Skype, Discord, or any VoIP app), it automatically adjusts the volume of other sounds, usually by up to 80%. This explains why your music, games, or system sounds suddenly become very quiet when you start a call.
In addition to that native function, Audio drivers and their enhancements can do their thingMany chips and drivers (especially those from Realtek) integrate "enhancements" such as bass boost, equalizers, headphone profiles, or cinema/gaming modes that don't always work well with real-time calls and cause abrupt volume changes, loss of sound "depth," or clicking when switching windows.
To complicate matters further, there are the software from the manufacturers of headphones and laptops themselves. Razer Synapse, Logitech G HUB, HyperX NGenuity, ASUS Armoury Crate, Dolby modules… They all typically have gaming or communication profiles that also affect volume, add attenuation, or change the audio mix as soon as a game or voice app is opened. When all of these things are happening at once, you get exactly the problem you're trying to solve.
Disable automatic volume adjustment in Windows
The first thing to do if Windows lowers the volume when starting calls is disable Windows communications featureBecause it's the setting that causes the system to lower the volume of all other sounds by default when it detects a call. The behavior is virtually the same in Windows 10 and Windows 11.
To access this setting you can use the classic sound commandFollow these steps:
- Press the key combination Windows + R, writes mmsys.cpl and press Enter. The traditional Windows "Sound" window will open, with different tabs at the top.
- Inside that window, enter the “Communications” tabYou will see several options that indicate what the system should do when it detects communication activity.
- Change the option to “Do nothing.”
- Finally, confirm with Apply and Accept.
From that moment on, when you make or receive a call on Windows 10 or 11, the system should no longer automatically lower the music, game, or sounds from other applications while you are talking.
Disable audio enhancements and effects that affect volume
The next usual suspect is the supposed "improvements" to audio drivers, especially if your motherboard or laptop has one. Realtek audio chipThese features add bass boost, virtual environments, equalization, or headphone simulation, but sometimes they cause the volume to change on its own or the sound to lose quality during calls.
For disable all these enhancements Return to the classic sound window. You have to do this:
- Press again Windows + R, writes mmsys.cpl and press Enter.
- This time, stay on the tab "Reproduction", where the list of output devices appears (speakers, headphones, HDMI, etc.).
- Right-click on the sound device you are using (your headphones or main speakers).
- Then select "Properties".
- In the new window you'll see several tabs. The one you're interested in is... “Improvements” or “Enhancements”, depending on the system language.
- Within that tab, check the box “Disable all enhancements” or “Disable all enhancements”.
- Then click on Apply and Accept.
This immediately disables all driver effects that may be modifying audio volume, equalization, or compression in situations such as calls or video calls.
Uninstall and reinstall the Realtek drivers (or try the generic driver)
If, despite everything, Windows still lowers the volume when initiating calls, it's very possible that the audio driver is corrupt, outdated, or simply poorly designedRealtek is one of the most common manufacturers. Although it usually works well, it's not uncommon for a specific driver version to cause volume issues, noise, or loss of call quality.
To check and update the driver, the quickest way is to use the Device ManagerSteps to follow:
- Writes device manager type it into the search box on the taskbar and open it.
- Inside, expand the category “Sound, video and gaming controllers”.
- Right-click on your audio device.
- Select “Update driver”.
- Leave the option selected. “Automatically search for updated driver software” and follow the instructions. If a newer version is available, Windows will attempt to install it.
If nothing is found or the problem persists, the next step is uninstall the driverTo do this, in step 3 choose “Uninstall device”. Confirm, wait for it to finish, and restart your PC so that Windows reinstalls a clean driver.
Use the Windows Audio Troubleshooter
If, after this, the problem of "Windows lowers the volume when starting calls" persists, it's not a bad idea Let Windows try to diagnose the fault on its own. That's what the built-in audio troubleshooter is for. It's not magic, but on some computers it has managed to detect unusual settings or blocked services that were affecting the sound. To run it, do this:
- Open Settings with Windows + I.
- In Windows 10, go to "Update & Security" and then to "Troubleshoot" and "Additional troubleshooters".
- In Windows 11, go to "System", then to "Troubleshooting" and "Other troubleshooters".
- Look for the entrance “Audio playback” and press on "Execute"The assistant will analyze the system for typical sound-related errors, such as disabled devices, stopped services, or driver problems.
It's also a good idea to disconnect any sound devices you're not using. (HDMI monitor speakers, secondary sound cards, old headphones, etc.), because the presence of many devices at the same time can cause conflicts in audio detection and routing.
Configure Discord, Teams, and other apps that lower the volume
Some communication applications bring their own attenuation settings that may be lowering the volume of everything else when someone is speaking. Discord This is one of the clearest cases, but it is not the only one: different programs allow you to reduce the volume of other apps to prioritize chat voices.
On Discord, the key section is the one for “Voice and video”Open Discord, click the gear icon in the bottom left (User Settings), and in the left menu, go to “Voice and Video”.
Scroll down until you find the section "Attenuation"You'll see a slider that indicates the percentage by which other apps' volume will be reduced when people are talking in your channel. If that value is high, your game or music will be significantly quieter whenever there's voice chatter.
Move the slider to 0% to completely disable Discord dimming.Save the settings, restart Discord, and try again in a call or voice channel to check if the volume remains constant.
In Teams and other business apps, Also check the audio options in case there are any optimization features that might be interfering. Although they don't always include controls as visible as Discord, sometimes there are "auto-adjust" or "auto-volume control" checkboxes that you should disable if they cause problems.
Detect conflicts with headphone and laptop software (Razer, ASUS, Dolby…)
In many cases the culprit is not Windows, but the manufacturer's own software from your headphones or your laptop, which is responsible for applying sound profiles and controlling the volume according to the game or program that is running.
- Razer headset with Synapse. Check the profiles linked to games. Open Razer Synapse and look at the profiles section where your linked games are listed. It's possible that one profile is adjusting the volume or activating an aggressive equalization feature when it detects a game or voice application.
- ASUS laptops with Armoury CrateOpen Armoury Crate, check the active profile, and locate any section that refers to audio settings or a "volume control module." Deactivate that module and see if the volume stops fluctuating.
- Laptops that incorporate Dolby (Dolby Atmos, Dolby Audio or Dolby Vision with sound module)Update the Dolby app from the Microsoft Store or the manufacturer's website and try changing the sound profile. Many users report that the "Dynamic" profile works well without volume fluctuations, while the "Music," "Gaming," or "Movie" modes are sometimes more stable depending on the device.
In general, the idea is to locate which software is trying to "own" the soundIf you have Synapse, Armoury Crate, Dolby applications, Logitech G HUB, HyperX NGenuity, etc., more than one of them might be adjusting volume, equalization, and enhancements simultaneously. Try disabling automatic control features gradually or even temporarily closing these programs to identify the culprit.
Could it be due to malware or a virus?
You've ruled out Windows settings, drivers, and audio software, but despite all that, Windows lowers the volume when you start calls. It's time to consider the less frequent but real possibility that there might be some kind of... malware manipulating system settings.
Some types of malware can modify audio parameters or sneak in as resident processes that disrupt system services, sometimes with the aim of recording conversations or simply as a side effect of other poorly designed functions. What can we do? Here are some options:
- Perform a full scan with Windows Defender. This antivirus comes integrated into Windows 10 and 11 and is usually quite effective. Open Windows Security, go to the "Virus & threat protection" section, and run a full or custom scan of all drives.
- Resort to third-party solutionsUse a program like Malwarebytes, Kaspersky, or another trusted antivirus. Install the program, run a thorough scan, and let it remove any threats it finds. Then, restart your computer and check if the volume behavior has changed.
- Manually inspect active processes from the Task ManagerPress Ctrl + Shift + Esc, go to the "Processes" tab, and check for any processes you don't recognize that are constantly consuming resources. If something seems suspicious, search its name online to confirm if it's known malware. If it's confirmed to be a malicious process, terminate it and uninstall the associated program.
Final tips and combination of solutions
There is no single solution that works for all cases where Windows lowers the volume when starting calls. In many systems the failure is due to a single cause. (the Communications tab, for example), but in others it's a combination of a driver with poor enhancements, a Synapse or Armoury Crate profile, and an active dimming feature in Discord.
The key is in discard layer by layer, patiently:
- First, disable automatic communication adjustment in Windows.
- Then, remove audio enhancements and test.
- Next, update or reinstall drivers, both for the sound device and the rest of the related components.
- In parallel, check the headphone and laptop software that may be controlling the volume.
It is very useful Try using different ports and devices. to confirm if the behavior is repeated and thus rule out a purely hardware problem in a specific connector or damaged device.
When everything is properly configured, A call on Windows should sound stable and of good quality, without sudden drops or loss of depth in the audio.Achieving this involves taming automatic volume functions, putting the drivers in their place, and making it clear to Windows and your applications who really controls the computer's sound.
