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 |

Fun is, Apple says on one hand you can have password protection in OF on intel macs, and on the other hand there's no OF in these…
 thanks I didn't now that… so how can we restore the equivalent (EFI) then? I'm going to dive into apple database as it's important for us. [edit] I found these which may be relevant (if it's on the Macpro side° Intel mac firmware updates Check yours is up to date. Reset the SMC of the MacPro reset also PRAM if it has not been done already. Once it's done or controlled, the issue can only be the driver itself (and it'd be a rare bug just for you) or the 828 mkII (which can have problems has we have already seen some). I'd strongly suspect the 828…

First... thanks for getting involved!! :-)
I have the latest firmware and I did a fresh 10.4.8 install with only LogicPro and the MOTU drivers. Again loss of sound output. I tried two different 828mkII interfaces (with different firmware/bootloaders) and I had the problem with both interfaces. There is a thread in Apples forums and some people suspect the Ram causing the problems. http://discussions.apple.com/thread.jspa?t...59&tstart=0 Maybe I find time to check different configurations.
