I've started working on the options menu for my game, including volume settings, starting with the global one.
There is either an issue with this, or maybe a misconception on my part?
As an example, I set the global volume to zero. Immediately all sound, music & speech in the current scene are muted,
as you would expect.
However, as soon as any sound is played or a character speaks as the scene progresses, volume is automatically unmuted & sound, background music & speech are resumed.
I can obviously get around it by setting sound, music & speech volumes separately, but that begs the question of the value of a global setting in the first place.
