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

Is there something else connected in firewire? the new intel macs don't have open firmware. ;-) it happens with nothing else on any firewire port. fresh OS install (only with latest updates and logic) showed the same problem. Would be great to know if other MacPros with 828mkII (mis-)behaving the same... This post has been edited by MatzeMillion: Fri 24 Nov 2006, 22:59 |
