Apple Logic Pro /LogicExpress Discussion

Hello!

I have a real weird problem - since today.

I can play music with iTUnes - everything is fine and played throughj the
Motu 828 mk2´s main out.
If I want to playback something with Logic Pro 7.1 or Quicktime or iMovie I
got weird high noises - no sound - only this noises - on all outs - even if
I change to headphones or the other outs (even the non-connnected outs) as
main out I got the high sounds through the main output - and nothing else.

If I start playback in Logic, I got "audio-midi synchronize" problems - right after starting playback.

If I change to internal sound everything is fine, Quicktime and all other
tools play just as would have been nothing happened.

It does not depened on which sample rate I choose.

I did reinstall the MOTU drivers (latest) - no help.

If I have something running in iTunes (playing back normal) and then start
Quicktime or Logic - the iTunes out is not hearble anymore - only the high
noises which sound like a digital problem.

I changed the firewire port - same problem.

I did not install anything new since yesterday only some widgets, everything
was fine when I went out of the house (system was put to sleep) - when I was
back everything was bad.

Same problem in Ableton Live 4.1.3

I have a Dual 2 GHZ G5 (one of the older systems), running on Tiger 10.4.1
since the release (with no problems), Logic Pro 7.1, Motu 828mkII, 2.5 GB
Ram, 2x internal Seagate 160 GB S-ATA drives, 1x external Lacie D2 Extreme
with Triple Interface 250 GB drive.

Any help, any hint what might have happened, any clues, any help whom I
should call (Apple? Motu? is it a hardware problem? software problem? would
be appreciated as for now I am not able to continue to work (and I have to
get done some remixes)...

All answers please also to my private email ( thedi[at]kiew[dot]org )  as this is urgent and I am not
reading this group all the time....

Help! Help! Help!
