Whenever I attempt to record or even just work with my files in Audiodesk, sooner or later my 828 unit will cease any playback and produce a piercing high-pitched feedback type sound until I turn it off.  It even persists to do it after I quit Audiodesk.  Sometimes it will even do it when the unit is on and Audiodesk isn't even open.   I am using a 1.6 G5 single processor and have run Disk Doctor and optimized it a number of times.  In fact, I am running Audiodesk from its own 120GB second hard drive with nothing else besides OSX.  I can't tell if problem starts because of playback, recording, or what have you--as it seems to do be able to start during anything.  I've restored factory defaults, installed all the latest downloads from MOTU.com and it just won't work.  We have used the unit on my friend's Powerbook G4 and it will sometimes do it on that machine, but it seems to be less often than on mine.  I also set it as my sound output in the System Preferences to see what would happen--and began to screech after not 6 minutes of iTunes. I need a solution to this extremely frustrating problem.  Please help me out.  Thanks.

Have you tried trashing the MOTU Audio System prefs and the MOTU 828 prefs (both at the same time) and restarting? You have to drag 'em to the Trash and empty it before restarting.

I'm still using MacOS 9 and a PCI-324 system and I rarely get this but trashing my MOTU Audio System and MOTU 423 prefs always sorts it out.

Because I don't own an 828 and I don't record in OSX, I'm not sure what the prefs file is named - it might be "MOTU 828" or it might be "MOTU Firewire." Just search your Home Preferences folder carefully to identify 'em properly before trashing anything.

If this doesn't help, something else is wrong, or you might even have a bad unit (it happens). Get in touch with MOTU Tech Support.
