Logic/g5/dp, No sound with Logic Options

[Z09]

Hi everybody,

I have recently installed Logic Pro.8.02 on my G5 bipro
everythings seems OK but I have no sound !
You have to know that just before I worked with Digital Performer.
DP is OK with the sound but I can't have sound when I open Logic.
DP and Logic are on the same computer but I never use them together…
Is anybody can help me ?
Thank you

Can you route system sounds (e.g. alerts, QuickTime, iTunes) to your MOTU device?

If not, there may be a driver problem, so you should check to see if there are any updates available from MOTU.

If you can use the MOTU in this way, try launching Logic, then press and hold "CTRL" as the software is loading. You should get a dialogue asking if you want to use the Core Audio driver. Select "no". When Logic has finished loading go to the Audio preference page we were looking at before. Click the "Core Audio" tab and activate the Core Audio driver with the little check box in the top left corner. Try switching between built-in audio and your Motu device (pressing "Apply Changes" each time).

After each "switch" go to your Loops browser and double click on any "blue" loop so it plays in preview mode. Are you getting sound with either option?

If your drivers are up-to-date and the above procedure doesn't jump-start the MOTU, you may need to trash your Logic preferences which can be found in:

User > Library > Preferences > com.apple.logic.pro.cs

These will be regenerated the next time you launch Logic so its not a problem.

Let me know if this doesn't work and I'll try to think of something else...
