Digi 002 RCA S/PDIF problem -> No sound thru DAC-1

HI, I just got a digi 002, upgrading from an Mbox. I'm trying to interface with my Benchmark DAC-1 via the RCA S/PDIF connection. The odd thing is that I sound through my DAC-1 when playing iTunes, but when I try and play audio from Protools, there is no sound. The dac-1's error light remains unlit, but there's no sound. I have the output set correctly in hardware setup to be the RCA outs and not the optical. Changing my system output to be the internal speaker doesn't help either. What am I doing wrong? This is my setup: G5 dual 2gHz 10.3.5 Digi 002, latest firmware Protools 6.7c3 Any info would be awesome!! Thanks, John

Hey, Just wondering if anyone had any ideas. Could it be some coreaudio problem? Thanks, John

Definitely sounds like an i/o setup problem, since iTunes makes sound. I had a hard time setting up the i/o matrix the first time. Had to go through that part of the manual a couple of times. Check it out.

...oh, good choice on the Benchmark. I have one on semi-permanent loan and it's really great.

I'm pretty certain (about 100%) the settings in Standalone Mode apply ONLY to standalone mode, and don't need to be set for ProTools mode.
