Oh wow, that's super interesting! In retrospect it's super clear that muting and unmuting the microphone system-wide will pretty much always work, since it's incredibly unlikely someone would need to have input on between push-to-talk activations, but for whatever reason, it never occurred to me. I use a cheap USB foot pedal to avoid needing to manage holding down the button while trying to do stuff in-game, and I'm realizing now how obvious it is that making it just toggle mute/unmute on each press rather than needing to hold down my foot would be _way_ more convenient!
