Digi 002 output distortion...help

[djwalter]

Hello everyone, I'm new and I've searched the forums and seen related problems but not my current one. I have a PPC G5 Dual 2.0 with a Digi 002 running PT 7.3.1. My problem is when I use the digi with the studio monitors I get feedback thru the monitors but not the headphone jack. I've hooked the monitors up to other sources and no feedback. I can bounce a session without feedback in the session. I've truned on the g5 with the digi 002 turned off and I still get feedback. If it was a firewire problem the digi wouldn't work at all right? I've done pretty much everything with the eception of adding a firewire card to the g5 and trying that. Thanks in advance for any input.

I apologize this post is in the wrong section, can admins delete this post please.
