Connect Button
The Connect button is available when the Core-
Audio Manager is launched and cannot connect 
with the Pro Tools hardware (such as when 
Pro Tools is launched and the hardware is dis-
connected or disabled). Before trying to con-
nect, make sure to quit Pro Tools and make sure 
that your hardware is connected and turned on. 
You can then click on the Connect button to ac-
quire the hardware.
Quit Button 
Use the Quit button to quit the CoreAudio Man-
ger. Be sure to quit any client applications before 
using the Quit button in the Manager. If any ap-
plications are currently attached to the Manager 
application when quitting, you may get an error 
message indicating that the Pro Tools hardware 
is no longer available. You may have to change 
the application’s preferences to use different 
hardware for playback or possibly quit and re-
launch the application for proper playback to be 
resumed.
CoreAudio Manager Preferences
If any application is launched prior to press-
ing the Connect button and you want that 
application to use the CoreAudio Driver for 
playback, you will need to quit and re-
launch the application for it to connect 
properly to the CoreAudio Manager.
