Hi,
My MBP acting up more than ever.
Using logic pro 9 I get these alerts -
I have an Audio box usb interface which has worked fine til now.
One thing i do have is a funny power adapter that doesn't show that its charging.
It also makes a constant crackling through headphones or speakers.
Please help!

I have no idea about those error messages, so can only give you general trouble shooting advice. Have you gone to system settings and set the input/output audio device? Sometimes I have to do it directly in Logic (I'm using X, don't know if it's the same for your version). To select/reset the audio i/o device in Logic, I go to logic pro>preferences>audio and choose from a drop down menu. In LPX, you can also choose to enable core audio with a checkbox. Sometimes unchecking, then checking this box again solves any issues.

Your problem seems a bit more specific than this and I don't think this will fix your problem, but it's worth a shot if you haven't tried already :) Good luck!

EDIT: I was also just having some issues with the audio on my rMBP after using HDMI and an audio interface and even after doing all the steps I mentioned above, I still had to reset the computer.
