Can't capture game audio without capturing ALL desktop audio

As the title mentions, I can't capture any game audio -- despite testing multiple games -- without capturing all desktop audio. If I capture from a console, it gives me three channels, Desktop Audio, Mic/Aux, and a separate audio channel from the capture device itself. But if I set up a game capture or window capture (for example, League of Legends or Raid: Shadow Legends) there's only the two channels, Desktop Audio and Mic/Aux. Is there a way to get that third audio channel specifically for the game? Is there a specific way to set up a source for that?

tl;dr: I want to capture audio from a specific source without needing to capture all other audio as well -- background music, audio from other games, etc.

Slight bump, I know that the computer is able to do it, as I can check the mixer and manipulate audio for each of those other programs, so I'm not entirely sure why OBS doesn't also give me a new channel when I capture the program.

Windows Audio does not run on a per-program basis, it exposes access/control to programs only on a per-device basis (your capture device being a separate audio device). This is not something OBS can circumvent.
To exclude or isolate on-system audio, you will need to use a third-party program like VBAudio VAC, or Voicemeeter (Banana/Potato). These will allow you to create virtual audio devices and 'cables' to mix and route them, though specific support for third-party software is out-of-scope for OBS Support.

If you google for 'Voicemeeter OBS exclude audio' though, there are a TON of tutorials on how to set it up.

Discord seems to able to do this fine so I don't see why OBS can't. I believe it might require a certain version of windows 10 and above for it work.

look, every program has its right to exist and its special use obs is designed for streaming, not for audio routing, there are other programs for that, i only use external hardware to mix my sounds and only play what i need, take a look at the voicemeter with a small midi controller you even have the possibility to control the audio without using the mouse
