I've been using DP for about a year now. I visit this site often, but don't usually post as I still consider myself a "newbie" with DP and I really haven't had any problems. Until now that is. I upgraded to a newerish Dual 2GHz G5 with 4 Gigs of RAM and OSX 10.3.7. My interface is an 828 MkII. I was on a Dual 1GHz G4 and DP 4.52 with no problems. Anyway, I updated to all the most recent versions of DP (4.62), Mach Five, the firewire drivers, etc. from MOTU's site. DP installed fine and opens and plays my old projects just fine. Here's the problem: I select an input from the 828, place the track in record, and get nothing. The meters on the 828 show signal, and if I select "Audio Pass Through" the raw signal comes through, but nothing on the meters in the mixer window and no sound through the mixer. I've got the input monitoring set-up to monitor through effects and always monitor when a track is record enabled. I've tried the other settings also and still no signal. Now here's the really strange part. If I open the Audio Monitor window, I get a level when I record enable a track. Still no sound or levels in the mixer window though. If I hit record, the signal is recorded on that track, but still I can't hear it while recording and no meters in the mixer window. The track plays back just fine and I get level meters in the mixer window. So basically, everything works, I just can't see levels or hear audio while recording. I've looked at the core audio settings, and all the studio and audio settings in DP and can't see any problems. This is really starting to look like a bug to me, but I thought I'd pick the pros brains here and see if anyone had any ideas. Sorry for the long post. I'm not the most conscise thinker.

Thanks for any ideas on this problem.
