Traktor freezes Song with an ugly "Rrrrrrrrrrrrrrrrrrrr....."

I have a very very strange issue and it seems, no one can solve it, even at NI...
So glad i found this forums and so i try it here.

Ocationally when a MP3 or AAC (most of the are bought from Amazon or iTunes) plays, after a minute or so, the playback stucks and repeats a short sample forever. It is not easy to describe, but it goes like this: "La la la hey hey hey la la heyrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr.. ...."

The Waveform is corrosponding to that. The Interesting part of this issue is, that the File seems to be OK and plays fine in iTunes. It also plays fine after relaunching Traktor.

I checked everything and i have no idea what the hell is causing this.

Traktor Pro 2.6.8 on a MacBook Pro Core2Duo 10.9.5, Numark Mixdeck
8 GB RAM, SSD for Software/Music is on HD

Please, any suggestions are appreciated!

I think I've had the same issue, and so have several others.

Although the title is about Yosemite the issue happens with Mavericks as well, please have a read and look at the videos etc.
