You mean AAC or AC3?

What files? How did you encode them? What device?

ACC music/sound file encoded with itunes. iPod nano 1^st gen.

That's AAC not ACC. What bitrate, and what revision of Rockbox?

Upload one of the files somewhere and i'll try to look at it.

That file plays fine for me, and fairly efficiently:

192% realtime, 41.6MHz

Are you using a lot of EQ and other DSP effects? Have you tried reinstalling rockbox to make sure you don't have a badly installed build?
