Audio Interface Is Not Recognized
Problem
When you launch Pro Tools it does not recog-
nize an audio interface, or a connected audio in-
terface is not available.
Possible Solutions
Turn off your computer and check to be sure
your cables are properly and securely connected
to your computer and to your audio interface.
Verify that your Hardware Setup dialog set-
tings are correct.
If you only have one interface, make sure it is
connected to the Accel Core (for PCIe) or HD
Core (for PCI) card.
Make sure Loop Sync, SuperClock or other
synchronization connections to your audio in-
terface are correct. Disconnect the clock source
from the interface and see if the problem per-
sists.
Using DigiTest as a Diagnostic
Tool
The DigiTest utility performs diagnostic tests on
the Pro Tools cards in your system. If DigiTest
reports that any of your cards have failed, click
the Info button next to that card. Write down
the information that appears and report it to
your local Digidesign dealer or to Digidesign
Technical Support.
