Macbook + MBox 2 Pro : audio device buffer underflowed
 

I am using MacBook (Black One) 2GHz Intel Core 2 Duo with 2GB of ram with MBOX 2 Pro, using PT 7.3.1 (cs2)
I was playing a session of just 2 tracks with NO PLUGIN and right in the middle of it, I got this 'audio device buffer underflowed' -6085 error message.
I am using this setup for concert play back and it's really a worrying issue because I am not sure when this error message will strike me again and if it happenes during the concert, it will be a disaster!

I don't daisy chain any HD with the MBox 2 Pro, and the fireware port is just for it and I am playing the session from the internal system drive.


THANKS!

Andrew
