The Communication Ducking
Windows 11 includes a feature designed for heavy VoIP users and remote workers called “Communications Ducking.” When the operating system detects incoming communication activity—like a Skype call ringing, a Microsoft Teams meeting starting, or a Discord voice chat initiating—it automatically lowers the volume of all other applications (like Spotify or your web browser) by 80%. The goal is to ensure you never miss a call over loud music. However, if you are a streamer, a podcaster, or someone who frequently plays games while chatting with friends, this aggressive, automatic volume ducking completely ruins your audio mix.
Disabling Audio Ducking
To retain full manual control over your audio levels and stop Windows 11 from automatically lowering the volume when you receive a call, you must disable the communications setting in the legacy Sound Control Panel.
Press the Windows Key, type Change system sounds, and press Enter. This will open the classic Sound Control Panel in a small window. Click on the tab labelled Communications at the very top right. Here, you will see the prompt: “When Windows detects communications activity:” followed by four radio buttons. By default, “Reduce the volume of other sounds by 80%” is selected. To completely disable this feature, click the bottom radio button that explicitly says Do nothing. Click Apply and then OK to close the window. Your game or music volume will now remain steady, regardless of who is calling you.
