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!!  Matthias MacPro 2,66 GHz, 5GB Ram, X1900XT, OS X 10.4.8, MOTU 828mkII with 1.4.2 driver, LogicPro 7.2.3, Waves 5.9.1 with iLok, Midisport 2x2 |

Hey, these forums are for help
 One thing you have not answered is have you something else connected in firewire? The fact 2 as different as possible 828 have the issue is smelling bad. Yep the RAM, but it'd be very "hairy" as a cause. And given the prices of it, not fun to swap just to check.

I checked many times with and without firewire HDs connected. In fact I tested the fresh install with no other hardware (only 23" Cinema HD, Mouse and Keyboard) attached to the computer. Makes no difference and the harddisks work like butter before and after loss of sound, even in a chain behind the 828.
I strongly believe its a driver related problem on MOTUs or Apples side. The ram swapping is very easy with these machine, but I really want to avoid it... QUOTE (lepetitmartien @ Sat 25 Nov 2006, 14:02)  Hey, these forums are for help

I was wondering if a solution to this issue was ever found? My MOTU 828 Mk II has worked faithfully for years on a G5. However, I am experiencing the same issues as MatzeMillion with my factory fresh Mac Pro.
.... and I see that MOTU just posted some new drivers on Wednesday...... let see what these bring. This post has been edited by rbailey: Sat 17 Feb 2007, 17:40 |
