High pitched noise etc and audio / midi syncing problems with MOTU 896HD

I've been having the noise / synching problem with my 896HD for ages. The only temporary solution is toggling the Optical Input & Output tabs on the MOTU Audio Settup window. But this is a pain in the ***. Sometimes I have to reset every 10 seconds or so. MOTU tech support said that there is probably a fault with the unit and that I should return it, but this doesn't make sense as I have tried other units and had the same problem. I have friends with 896HDs who have never had a problem, and when we switch units I still get the problem.
Does anyone know what's going on?

Cheers.

It's definitely a driver problem. Just keep the Opitcal Input and Output set at ADAT. The noise should stay gone.

That's the thing though...it doesn't stay gone. If it happens it will reset things, but it can return within the minute sometimes. I've tried leaving it on both 'ADAT' and 'None'. It's been going on for over a year, and in that time I've had driver updates, logic updates, OSX updates, and even switched actual 896HD's. I'm running out of things to update, besides the computer itself! If it's just a driver thing, then how come everyone doesn't get this problem?

I have a 828MKII and I've had the same noise you described.One thing that causes it for me is when I connect my Canon DV camera to the front firewire port on my G5...in fact it just happened an hour ago.Unplugging it makes the noise go away.Have you tried the factory reset procedure? I'm not sure if it's the same as the 828 but try that http://www.motu.com/techsupport/technotes/document.2004-06-16.6405589976
Also, have you tried different firewire cables? You'd be amazed at the problems FW cables can cause...good luck!

hmm. I've had the problem you described, but as long as I keep my settings to ADAT, it doesn't return. If that doesn't work, I don't know what to do then, unfortunately. All I can suggest is to search http://www.unicornation.com/ as they might know something.

have you tried resetting the 896 to factory specs by whatever button combo it calls for? the same things happens with the traveler and resetting solves it for a few weeks.
