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 |

reset the nvram like explained here:
- start up in Open firmware (command-option-o-f on start up) - at the prompt type, followed by a return: set-defaults reset-nvram reset-all It'll reboot with NVRAM back to defaults values. If the issue is a wrong bus speed somewhere, it'll cure it. Is there something else connected in firewire? -------------------- Our Classifeds • Nos petites annonces • Terms Of Service / Conditions d'Utilisation • Forum Rules / Règles des Forums • MacMusic.Org & SETI@Home
