First of all: I use the current version of Twine (2.2.1) and SugarCube 2. And I've read the audio macro list, but I still don't understand how to do that.
What I want is to fade out whichever audio file is currently playing while starting to play a new one. A simple transition, basically. But apparently you can't use "fadeout" for whole audio groups, just for playlists. So what I tried is creating a playlist with every audio file in it (in StoryInit as recommended) and then say in the passage: <<playlist "AllCachedAudioFiles" fadeout>> <<audio "NewAudioFile" play loop>>
It doesn't work, it doesn't fade out. Could it be that it doesn't work because "NewAudioFile" is also within the "AllCachedAudioFiles" playlist?
