How to make an mute/unmute button?

@richard_simms I also found your info useful! Is there a practical way to do the opposite with a Solo button, and by that I mean:

  • I have various sounds (FMOD events with Programmer Instruments) playing that are in one (or more) mixer groups
  • I want to press a button in the game that MUTES all the other sounds, so it should be able to detect what everything else is in a group
  • It should not mute certain other mixer groups, such as system UI sounds, and the like.

Basically the in-game equivalent of pressing a SOLO button in an FMOD event track. What might the logic for this look like, or is it considerably trickier?
