Motu 828mkii With Reason/live, No sound from sequencers to 828 Options

[Rhythmproject]

Hello. I'm having trouble figuring out why I can run sound through firewire that's coming from iTunes or any other program that outputs audio, but not from software sequencers. My setup includes an 828mkII, MTP AV, and an XP-80 and I'm running Reason and Live on a G4 laptop. I want to be able to send sequences or sessions from the programs through the firewire instead of the 1/8" output (which would take up two more of the inputs on the 828), so I changed the coreaudio default input, output and system output to the 828, and in both the programs set the audio card and/or outputs and inputs to the 828. The built in audio card seems to work just fine, so I know the programs are working because I can listen through the analog output on the laptop, but when I have things set to the 828 I get some nasty high pitched business coming out of my monitors. I swear I had both live and reason working through the firewire once before. Am I forgetting some major detail? Can anybody shed light on this problem? I'd greatly appreciate some insight. Thanks.

Thanks for your reply. I just spent about half an hour on the phone with MOTU and they didn't seem to know why things wouldn't work for me...the only solution they could come up with is that maybe because demo versions of programs (like the Reason and Live I'm using) ouput lower sound quality than the full blown versions that maybe it wasn't making its way through the firewire. ???? I went into Live's preferences but never found a section that pertained to channels or selected tracks for listening. Maybe demo preferences are limited? or maybe I just missed it. I reinstalled all my drivers for the software and the 828 and I'm still getting a nasty screeching noise. Any tips?>>>they're welcome. Thanks again. P.S. While all this is going wrong I'm getting great sound out of my iTunes through the firewire so it's obviously a software thing...
