Audio glitching and crackling in Audition CS6 multitrack for MAC

[evans751486]

Hey, I just booted up Adobe CS6 on my Macbook Pro (Model Identifier: MacBookPro11,1, Processor Name: Intel Core i5, Processor Speed: 2.6 GHz. OSX 10.9.5) after some time. I remember in the past there were a few audio glitch problems but not too bad, but now the audio glitching and crackling in the multitrack is pretty unbearable. And it picks up in the export as well. Any idea whats the problem and how to trouble shoot? I'm thinkin it could be a soundcard problem, or maybe I need to freeup more space on my computer or something, but it seems fine. Any help is much appreciated and there's an example video attached.

And if someone has a lead to any free version of adobe on Mac i'd appreciate as well to try another version. Thanks!

How do the individual recordings--particularly the voice--sound if you solo them and listen to them by themselves?

They crackle. Not horribly though. It gets way worse in multitrack

What happens when you turn off all the fx or 'freeze' each track?

Have you tried increasing the buffer size?

Having listened to it, I'd be looking at the buffers too...
