Question / Help How do I make that the browser's sound is not caught?

[Foreld]

I record Footages from games, often leaving someone's stream in the background. But OBS picks up both the sound of the game and the sound of the Browser. Is there any way to hide the sound of the Browser from OBS? I don’t need, as is usually shown in the guides for VoiceMeeter, to record separately the sounds of Skype, Discord and others. I just need to record the sound of only the game. How to do it?
Browser - Google Chrome.

You need to configure the game to output its sound to some specific Windows audio device. Many games allow this, but not all. It's within the game's audio settings.

If your game allows this, go and install a virtual audio device, for example this: https://www.vb-audio.com/Cable/index.htm

After installation, direct the game to output its sound to the new audio device. Your game is now silent, because it doesn't output to desktop audio any more. To re-establish sound output, open the sound control (Windows settings->System->Sound, then top right corner sound system control or what it's called in english). It's the old Windows 7 sound control center with the tabs Playback, Recording, Sound and Communication. Go to the Recording tab and open the properties of the virtual audio device. Go to the second tab and activate "Listen to this device" and activate output either to the default audio device or to your speakers - wherever you want to listen to the game audio. This re-establishes audio output from the game to your speakers or headphones.

In OBS, in Settings->Audio remove the previous audio device (probably "default") and replace it with the virtual audio device.
This way you "tapped" the game audio before it is mixed with all the other Windows audio.
