sound assertion problems and Internal maximum value

Hello,

I'm working on a Macbook Pro Retina, mi-2012, 2.6 GHz Intel Core i7, 8 Go 1600 MHz DDR3, Intel HD Graphics 4000 1024 Mo.

I'm receiving 2 kind of messages on the console:

the 1. ones are Internal maximum Value:

And the second ones are sound assertion messages:

It seems that it wakes my computer up and my computer keeps running (I hear the fans turning) even if the screen is "closed".

Any idea?
