Problem recording with DP 5.13 and Profire Lightbridge

[jumpin]

I'm using a Profire Lightbridge and Digital Peformer to record a test track via
any of my preamp devices with ADAT out. All I get is an awful vocoder type
signal on the track. Playback works just fine with no clicks and pops etc...
I don't believe this is a wordclock problem because of the good playback and
seeing solid sync on all devices. It also happens just the same in any wordclock
setup I've tried (all of which work fine on playback).

I guess I need to figure out whether it's Digital Performer or the Lightpipe.
Does anyone know of a free program I could try to cut DP out of the loop to
see if the same thing happens?

Thanks,

Jon
