I'm using Steelseries Sonar and I quite like it. I also quite like Steam Background recording, but the issue is that even when setting it to record all system audio, or selecting programs manually, it won't pick up any other audio channels on my PC, namely the ones created by Steelseries Sonar.

Ideally I'd like to be able to record Discord etc. in the background of my clips so it doesn't just sound like I'm talking to myself when clipping something that happened in Rematch or Battlefield 6, for example.

I'm visualizing this as adding some kind of checkbox for all the audio channels on the PC, which would support virtual audio devices like Sonar.
