828mkii Sometimes Stops Working Options

[MatzeMillion]

Hi everyone,

I have a strange problem with an 828mkII and a MacPro. Sometimes after closing an application with motu sound output (logic, a game, quicktime, etc) the interface stops working. Its still avaliable, but don't play back any sound. Only way to get sound back is a restart.

It does happen only with a MacPro. With an Intel MacMini, a MacBook Pro and Powerbook G4 evertything is fine.
I tried a complete reinstall, other cable, removing other devices, factory reset, unplugging / reconnecting, switching on/off, unloading/loading kernel extensions, booting the MacPro via firewire from a MacBook Pro, tried an other 828mkII interface, etc.
Nothing helps.

When it happens, the MOTU Midi interface is greyed out in Audio-Midi-Config.
Quicktime is hanging like 10sec when trying to play back sound.

Is there anyone with same problem or with a MacPro and no problems?

Thanks for any reply!!

Hello
I am new to the forum. I have had issues with my 828MKII and my G5,Macbook Pro,Macmini and Mac Pro. So far this is what i did to resolve the problem. I purchased an M-Audio 410 for my Live Kore2 rig and my Macmini. I spent too much time but with this advise I pray some of you get your $ worth from your Motu 828MKII.

I took MatzeMillion's advice. Please see below;

Try a factory reset - push the Setup knob, turn it all the way to the right and follow the directions on the LCD.
- Try setting both your Optical Input and Optical Output in the MOTU Console to ADAT.
- Try a different Firewire cable.
- Try removing all other Firewire devices.
- Try different Firewire ports.
- Try toggling the red voltage switch on the right side of the unit with the unit OFF. Do this 5 or 6 times, then set it to the correct position and try again.
- Try the unit with a different computer, if possible.
- If you use a PCI Firewire card, check to make sure your card uses the Texas Instruments or Lucent chipset.
- Try reinstalling drivers:

I also did the following;
- I reset PRAM
-I also repaired my disc permission
- I had to re-install the latest driver on Motu's webite 3 times

So far i have did this with my Macbook Pro. I will post new info on the Macmini. It was very unstable but I will check it out soon. I wont install any drivers for my Mac Pro. It is my Pro Tools HD3 rig.

Thanks for taking the time to post this info.
