Audio Interface Isn’t Recognized
(TDM Systems Only)
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 the correct Pro Tools cards and to your audio
interfaces.
◆ Verify that your Hardware Setup is correct;
check to see that you have selected the correct
Interfaces for each I/O card.
◆ If you only have one interface, make sure it is
connected to the HD Core card (Pro Tools HD-
series systems), MIX Core card (Pro Tools MIX-
series systems), or d24 card (Pro Tools 24 sys-
tems).
◆ 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
(TDM Systems Only)
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. Refer to your Getting Started
Guide for specific DigiTest instructions.
