Sound volumes of zero aren't really zero

This isn’t a bug so much as a suggestion. In the sound volume settings, setting anything but the Master Audio to zero doesn’t actually set the associated sounds to muted. Like if you set the voice volume to zero, you can still plainly hear them talking. Same with music, SFX, etc. It just seems like you should be able to set these things to zero and have them not play at all. Like if you wanted to listen to your own music while turning the MYZ music off, for example.
