How to check when a bus is playing back and mute it?

Hello

I'd like to know when there is an active MasterAudio playback like this: (MasterAudio.PlaySound("Alphabet", 1f, 1f, 0f, currentLetter);

so when a new letter is changed quickly the old one is faded out so the new one plays back.

Does that make sense?

This case applies specifically to when users quickly change letters. In this case the new MA PlaySound plays back on top of the old one.


Thanks
