bl0odoolo0p Posted May 2, 2009 Share Posted May 2, 2009 Hi - I am having the worst time with this. Logic keeps dropping the connection to my audio nterface(s). It is happening both with a metric halo 2882 and when I disconnect that and connect up an m-audio firewire 410. Sometimes I get no error message when this happens and sometimes I get this message: Error while trying to synch audio and MIDI Sample rate 43092 recognized Check conflict between Logic and external device Every time I get this message the sample rate is different, but it's always a weird random number. I've trashed everything there is to trash, I've updated everything there is to update. I've run every diagnostic/permissions repair/disc repair/cache emptier/etc. etc that I know about. I've "reset all midi drivers" in midi prefs. I tried running the system from another user account. Whenever it happens I can re-engage the audio by resetting the sample rate in the Project Settings/Audio (switching from 44.1 to something else & back) but it just keeps happening over and over again. Any ideas? Am I missing a hidden corrupt pref? This has been going on for a few days and it's driving me nuts already. Logic Studio 8.0.2 Metric Halo 2882/M-Audio FIrewire 410 MacBook Pro 2.33 GHz Intel Core 2 Duo OSX 10.5.6 thanks much for any help/ideas... david f Quote Link to comment Share on other sites More sharing options...
o2music Posted May 3, 2009 Share Posted May 3, 2009 it happened to me just the other day. what i did was delete the latest components that i installed recently and reinstall one by one to find which one caused the problem. and it turned out to be my PSP delay. i hope it works for u.

bl0odoolo0p Posted May 3, 2009 Author Share Posted May 3, 2009 I'll try this - though it's been a little while since I've added anything..maybe a month or so. But I'm ready to check out any possibility. thanks much for the idea - I'll let you know what happens.. -df Quote Link to comment Share on other sites More sharing options...
bl0odoolo0p Posted May 3, 2009 Author Share Posted May 3, 2009 Damn - still happening... Stripped out ALL of my AU components and still got the same error message/loss of audio:( Any other ideas out there? I REALLY have to solve this soon - falling behind on everything... thanks, -df Quote Link to comment Share on other sites More sharing options...
David Nahmani Posted May 3, 2009 Share Posted May 3, 2009 Try switching the Core Audio device to built-in audio, work for a while and see if the problem disappears? Also: are your interfaces' clocks set to "internal"? (they should) Quote Link to comment Share on other sites More sharing options...
bl0odoolo0p Posted May 3, 2009 Author Share Posted May 3, 2009 Hi David - Just tried that after you suggested it and it happened again - I didn't lose audio, but Logic stopped and I got the error message posted above. What could this be?!? Do I need to re-install the OS? Any other ideas? thanks, -df Quote Link to comment Share on other sites More sharing options...
fader8 Posted May 3, 2009 Share Posted May 3, 2009 Try removing the Digi core audio drivers. Remove the "Digidesign CoreAudio.plugin" file from: Library/Audio/Plug-Ins/HAL folder. Digidesign/M-Audio core audio drivers can screw up other interface drivers, even if the device isn't connected. It's really quite amazing how they're able to do this.

benulous Posted May 4, 2009 Share Posted May 4, 2009 I had the exact same problem with my FW410 after about a year of using it w/out it issues. I had to send it back to M-Audio twice to get get fixed but, the problem persisted. They eventually finally just replaced it and now the new one works fine.

bl0odoolo0p Posted May 4, 2009 Author Share Posted May 4, 2009 Well, I've tried all of the above - and much more - and the problem persists. But I have noticed that if I am offline that it seems to happen much less. And I can almost MAKE it happen just by going online and clicking on a link or two in Safari. Does that make any sense at all? Is it a significant clue or just random coincidence? This is going on week two - I've been doing computer midi/audio for a long time - since Notator/Atari and I've never had a problem last so long as this has. I'm really getting desperate... thanks, -df Quote Link to comment Share on other sites More sharing options...
benulous Posted May 4, 2009 Share Posted May 4, 2009 Do you have an external firewire drive daisy-chained off the FW410? Also, do you have the same problem when using the other firewire port? Quote Link to comment Share on other sites More sharing options...
triplets Posted May 4, 2009 Share Posted May 4, 2009 Is your laptop plugged in or running on battery when it happens? Quote Link to comment Share on other sites More sharing options...
bl0odoolo0p Posted May 4, 2009 Author Share Posted May 4, 2009 My laptop is always plugged in and it happens when I have nothing but the interface connected. I only have one firewire port. But I don't think it's the external devices situation because it happens even when I use the built-in audio. thanks, -df Quote Link to comment Share on other sites More sharing options...
triplets Posted May 4, 2009 Share Posted May 4, 2009 Have you tried uninstalling the M-Audio driver if you're planning on using the Metric interface? Quote Link to comment Share on other sites More sharing options...
