Core Audio Error-speedio, Error 709 and digital noise Options

[bloodychoir]

Hi, I'm running Logic 7 on a dual 1.8 pm on 10.3.5. When I load Logic with my Speedio usb interface already recognised "Core Audio Error 709" appears. I can't find the help on this error. This might be as simple as my usb interface needing to be unattached prior to booting Logic 7, as it seems to go fine then, but should I have to do this? I bought the Speedio for laptop taping, but for the time being it will have to do for a main card too.

Also, and I think this has been covered somewhere, I'm hearing way too much digital noise when monitoring both from the pm and via the interface. I have the system output on built in audio with the default output on the interface. I'm worried this may cross over to the recording. Any help?
