Capture audio from a single source

[Arches_14]

Hello to all.
I am not able to record only the audio of the source I have decided, without obs going to capture the audio of everything that my computer plays.
in a nutshell I would like obs to record a source and its related audio without recording the other sources that I am playing at that moment.

Windows does not handle audio on a per-program basis, it works on a per-device basis.
You will need to use third-party software like Voicemeeter or VBAudio VAC to accomplish what you want.

Google search for 'how to exclude audio in obs', as there are a LOT of tutorials out there on how to do this, and support for third-party software is out-of-scope for the OBS forums.
