Audio clips (narrations) are playing on the wrong slide(s)

I too am experiencing this issue, but now the old fix of opening the audio file, playing a few seconds, closing and saving is not working- even when I deleted the wrong audio track from the project file-- SL is still playing it. I checked the media library and it says that the file is only playing on one slide, and marks the correct one, but almost all the audio tracks are scrambled when I preview or publish... I'm using the most current version/update of SL360. Have tried publishing both Flash and HTML5 and the same thing is happening. The first few slides play fine, and then all of sudden it just randomly starts playing the wrong tracks. What gives?

EDIT: I tried turning off the Optimize Audio option in publishing settings and that seems to have fixed the problem! But it would be nice if we could still optimize audio without SL mixing up audio tracks...
