I was doing easy with the tutorial walkthrough mode and it keeps repeating a sound.  I had to disable the Sound Effects so it wouldn't be annoying. 

 

Just thought I would let you guys know.

I had that one too. You can just turn off the tutorial (instead of all the sound effects)

I also get this error. I think that it is triggered when a tutorial text is about to be closed which triggers the looping sound effect to play.
