Logic Pro/Express 7: Core Audio driver cannot be selected

In some situations, the Driver selection menu and other settings in the Core Audio preference pane of Logic Preferences (from the Logic Pro or Logic Express menu, choose Preferences, then Audio, click the Drivers tab, then click the Core Audio tab) may appear dimmed (unavailable).



This happens if Core Audio is disabled, which can occur after you remove your Logic preferences or install Logic on a fresh system without running the Setup Assistant.

To select a driver:

1. Click the Enabled button in the upper left corner of the Core Audio pane in the Preferences window. A dialog appears, asking you to reboot Logic:
   
   
   
   
2. Click OK. All the settings should now be accessible.
   
   
   
   
3. To select a driver, choose an audio interface from the Driver pop-up menu.
   
   
   
   
4. Another dialog appears, asking you to reboot. This time click Try (Re)Launch to initialize your selected driver.
