X-HD: Inputs and outputs not all showing up in Pro Tools

Problem:

"I have the AD-16X, DA-16X and the X-HD cards connecting them to Pro Tools. In the Hardware Setup in Pro Tools, I only see 8 analog inputs and outputs and 8 digital inputs and outputs. How can I choose 16 analog inputs and outputs?"

Solution:

The channels that show up as digital in the Pro Tools Hardware Setup are actually analog 9-16 when using Apogee devices.
